Sodium Thiosulfate for Heavy Metal Detox, Calcifications, Candida

WARNING!

Almost all tap water we drink is chlorinated. The issue is that while some municipalities use Chlorine, many use Chloramine instead, mainly because it's cheaper and in certain conditions more effective.

The problem is that Sodium Thiosulfate combines/reacts with Chloramine and that releases Ammonia, which we all know is very dangerous!

This must be addressed. Benefiting from Sodium Thiosulfate's benefits while enhancing Ammonia levels is a real danger.

Any feedback/precautions/fixes are more than welcome :)

Many thanks,

Normal drinking water is chlorinated at 4 ppm, sodium thiosulfate will dechlorinate the water, for a commercial aquarium product at 2 drops of the product for 1 gallon of water with 4 ppm of chlorine ( same as city drinking water). On the web, a sodium thiosulfate calculator was found that indicated that 53 mg of sodium thiosulfate per gallon of water with 4 ppm of chlorine, the chlorine will be deactivate. go here http://www.cnykoi.com/calculators/calcdechlor.asp

Now.. maybe Ted can answer this, if 2 drops will dechlorinate at 4ppm for 1 gallon of water, then 1 ml contains 650 mg of sodium thiosulfate or a concentratrion of 65%. Is that correct, 65 % concentration to get 2 drops to dechlorinate 1 gallon??? Or is there other agents added to the product which synergestically work to dechlorinate, with a lower concentration of sodium thiosulfate?

Hi Debra, you can purchase sodium thiosulfate from Clark Rubber in Australia. It is called 'Chlorine Remover' and is available in 500gm containers. It is the crystal form. Hope this helps.

BETTER BUT WITH SIDE EFFECTS

Thiosulfate report: Be careful when using thiosulfate as a toxin remover, chelator: The thiosulfate may also remove too many critical nutrients, like copper, calcium, iron, magnesium; if used without a plan.

I used a fish aquarium water cleaner that I bot in a pet shop; with a odd brand name. The specifed use of it was to clean the tap water of chlorine, it contained sodium thiosulfate plus EDTA as a liquid solution. I found the ingredient list on the distributors website msds sheet. They were not listed on the bottle label. 30% sodium thio-sulfate and 10% EDTA. My purpose was to try and chelate insecticides, pesticides, arsenic, and heavy metals from my tissues.

I and a 2nd person took 2 drops, in water, twice per day, 6 days per week, for 4 weeks. [ 2 drops X 2 t/d X 6 d/wk X 4 weeks]

By the end of week 3 I was having muscle spasms in lower legs, in mornings, while in bed. The 2nd person also experienced some muscle spasms. This indicates a deficiency symptom of calcium, or magnesium, or maybe iron...... This occurred until we stopped the mineral chelator.

By week 3 I began to experience chronic lower back soreness and pains, while doing no physical labor. The lower back area seemed to be loosing calcium at the vertebraes and the lower back seemed to be degenerating, for no apparent reason. As if I was experiencing a calcium deficiency in the vertebrae bones..... Until I stopped the mineral chelator.

By the end of week 3, the 2nd person was showing signs of a copper deficiency, despite supplementing with copper. This showed up as sub-dermal heamatomas, or capillary fragility, and bleeding under the skin after a mild bump or a scrape. She had previously been cured of this sub-dermal heamatoma symptom by supplementing with 2 mg of copper, per day. She was still supplementing with copper, but the capillary fragility was coming back... Until she stopped the mineral chelator.

After 4 weeks we stopped the experiment, and within 2 days our symptoms began to reverse themselves. It is now day 3, and we are better still. The symptoms are now 75% improved, after only 3 days. Leg cramps gone, sub-dermal heamatomas gone. Lower back soreness is 60% better.

This experiment proves to me that the sodium thiosulfate [plus the EDTA in the formula] is a powerful chelator of metals, and therefore is potentially capable of chelating heavy metal, etc. but You must restrict it's use to short periods of time; maybe 1 week per month for general chelating. And supplement heavily of nutritional minerals while on it. In the future, I would only intake it One time per day, at bedtime, away from food. In a cycle of One week on, 3 weeks off.

It would be good to keep in the house for emergency use for accidental poisonings, or suspected poisonings. Perhaps taking it for 3 days after the suspected poisoning occurred, as insurance.

I hope this information helps someone else.

Thank you! Lisa

Hi Susan, I just thought I'd give a link to where I got my lab grade sodium thiosulfate. I remember being a little apprehensive about where to get it so, I thought this might help others interested in using it. There's enough in here to last a lifetime! ;) It's very inexpensive and I've been using it since last Nov. Also, it's the crystal form (or rice pellet size).

http://www.sciencecompany.com/Sodium-Thiosulfate-Pentahydrate-500g-P6376.aspx

Take care, Lisa

Hi Susan... The Sodium Thiosulfate in your link seems to be OK. For the right doasage, just add one flake -- about the size of a grain of rice -- to a glass of water and drink it. This will help to remove chlorine and heavy metals from your body.

Bill from san fernando, can you check to see if this the right sodium thiosulfate also?

sodium thiosulfate listing.

THANKS!

Hi this is for DC in the UK, Dont know if you will get this as the thread was back in 2010.

Please could you tell me where you bought the Sodium thiosulfate you used for mercury detox. Did you work out the dilutions/dosages ok and what has been the result of treating yourself with this..... Did you have any ill effects?. Would be grateful for response, thanks a million

regards Rachel

I just purchased ThioSulfate, I'm gonna use it to help rid ammonia out of the brain. I'll be taking Glutamine as well.

The pentahydrate part next to it just means it has 5 water molecules associated it. So yes it's the same thing but if you heat it you could actually vaporize the water and get an even purer concentration of the STS. But it's not really necessary.

Hi Rasha, Vikash Pharma does the re packing of this product at 7-A, Aghadi Ind. Estate, Ram mandir Rd. Goregaon (E) Mumbai-400063.

However I got it in the powder form from some shop at Princess street, some time ago. That is the place where lot of shops are there who sell all sorts of chemicals, one has to really search. If you need any further information you can call me 09322887066. I live in Mumbai.

I have been using Sodium Thiosulphate for a number of years now.

I use it to remove heavy metals and as an anti-oxidant to help me sleep and it works pretty well. I believe its fairly hard avoiding processed foods and water nowadays, so this is one of the reasons I take it regularly.

I take about 8 drops a day in water -- I have the 10% Sodium Thiosulphate solution sold for fish tanks. But Ted describes that he takes the flakes -- he takes one flake of ST -- about the size of a grain of rice -- in water.

I also eat cilantro or coriander leaf in salads and drink green tea regularly which also helps to remove heavy metals. Sodium Thiosulphate is also used in much larger amounts as an IV buffer or flush after a cancer patient has had chemotherapy. Sodium Thiosulphate also removes arsenic as well as cyanide from the body. Very useful stuff.

Supplementing Lugol's Iodine (Aqueous Iodine) has similar action, but acts to remove Fluorine and Bromine from the body. It also removes mercury, lead, cadmium and aluminium too.

To make the 10% ST solution, just add 10 grams Sodium Thiosulfate to 90 grams (ratio 1:9) of water and you will have the 10% solution so you can use drops if you want.

The bottle of tap water conditioner that I bought is 30% sodium thiosulfate and 9% EDTA tetrasodium salt. Would it be safe to put say 1 drop of this in a glass of water?

I found one dechlorinator at Petsmart that listed the ingredients. They are sodium thiosulphate, EDTA and polyvinylpyrrolidone. Is the PVP a problem to consume? I read online that it is in all kinds of things, including tylenol, personal care products.

you can order medicine on ukraine.

2 producers thiosulphate of sodium as solution for injections:

Darnica (Ukraine, Kiev), Biolek (Ukraine, Kharkov)

Could someone inform-either via email or here on the board me on either of these?:
1) Instructions on how to mix a dry Sodium Thiosulfate, so that I can consume it?

2) In lieu of the above, could you provide me the name of an appropriate brand of liquid Sodium Thiosulfate that they sell in fish stores here in the US. Most don't have ingredients listed. I went to an aquatic shop yesterday and was sold Prime. After further research, it appears this product contains more than Sodium Thiosulfate and since those ingredients appear to be proprietary, I don't want to risk ingesting this stuff. Thanks.

Thanks, Isabelle. x

Hello! I just prepared it again today for I used my first batch already. 10 gr sodium thiosulfate 90 gr of distilled water = 10% solution. If you have a scale it is easy. Put your container on the scale, pour 10 gr of sodium thiosulfate(rice)and add carefully 90 gr of water. If you have to work with a measuring cup it is a little more difficult; density is 1. 667 g/cm3 but the solubility is 20.9g/100ml so if I understand well: if you make a saturated solution it is automatically a 20% so by adding the same amount of water in the saturated solution you get a 10%. Good luck!

Hi again

I got a 99. 9% pure ST and it has arrived in crystal form. So Ted's 10% solution and 10 drops a few times a month means this version I have must be diluted. To create a 10% solution I'll need to do some quite specific weights and measures calculations with solid and liquid conversions unless anyone has used the solid form or has some simple teaspoon/tablespoon quantities to suggest?

Cheers for now
DJ

Thank you everyone for your input. I will source the items and start a programme and keep progress, updating when needed.

Bessings,

You could give Iodine a try! About as cheap, maybe more so. But only if it's LUGOLS. You'll have to find out if you can get the original 5% so-called LUGOLs where you live, or only a 2. 2% diluted version.
See around slide 43 here:
http://www.scribd.com/doc/1959949/IODINE-Solution-to-Healthproblems

Iodoral is a tablet infused with LUGOLS = 2 drops of 5%= 12. 5 mg total Iodine. So 50mg is 4 Iodoral tablets. I looked at a few websites to find out the per gram cost of I in this tablet compared to LUGOLS drops, and it's quite a difference! Ten times as much per gram, and more, for the convenience of a tablet. 50 mg of 5% LUGOLS would be 8 drops. I don't know if one can start right at DAY 1 with 50mg I ingested. The info in the slide comes from Dr. Brownstein, but his site seems to have only videos for purchase and not much free information:
https://www.drbrownstein.com/homePage.php

Hi Dj. . . You should be able to buy Sodium Thiosulphate at any aquatics shop in UK. This form should be pure enough because this form of Sodium Thiosulphate has to be pure, because it is used to eliminate heavy metals and chlorine from the water of live fish tanks. I've used this form of ST for about the last 3 years with no ill effects.

You can also eliminate heavy metals by supplementing with Lugol's Iodine or an Aqueous Solution of Iodine(British version). Iodine also usefully eliminates toxic bromine and flourine from your body as well.

You can also eliminate heavy metals simply by drinking green tea 3 times a day or eating half a cupful of Cilantro(coriander leaf) in salads three times a week. Using this diet method will get rid of your heavy metal problem in about a month.

Hello! Sodium thiosulfate aka hypo aka rice is sold pure in photo shop. I am using it whithout any ill effect. Good luck!

Hi there

I am mercury toxic as shown via blood and urine tests.

have found several sodium thiosulphate suppliers in the UK (chemical firms)that appear to offer to the photographic industry. It is marketed as solid and has the letters LRG in the description. Prices appear good at about £10 per 500gm

Are all forms of SD safe to take? and does anyone know what dose might be a safe starter for mercury removal?

Appreciate any help in this

Cheers DJ

Hi Joe...Yes, use 6-10 drops of 10% Sodium Thiosulfate(ST) in a full glass of water. If you have a 30% ST solution, then it will be 3 times as strong as the 10% ST solution. So just divide the original dose by three -- and take 2 - 3 drops of the 30% solution in a full glass of water.

Also, as Ted has said, the first time you take the Sodium Thiosulfate, you may well get diarrhea. But this is just the ST purging the heavy metals etc. from your bowels and is normal. This should only happen once, the first time you take the ST.

Also, ST is not something that I take every day. If you have heavy metal poisoning, then I would take this twice a week. I would also eat cilantro leaves(half a cup) three times a week in salads as well as drink green tea every day. The ST, along with these simple dietary protocols will all help to rid you of heavy metals from your body. I take ST about once a week now, I also eat plenty of Cilantro and drink green tea regularly.

The mag chloride can be taken orally as well. If you're using mag oil, then take 10 drops of mag oil in a full glass of water every day. If you get loose stools or diarrhea, then just cut back the dose. However, the best way to take mag oil, in my opinion, is transdermally -- rubbed onto and absorbed through the skin, because more magnesium is absorbed quicker and there will be no stool or bowel problems because you are absorbing the magnesium directly into the blood.

If you want to confirm heavy metals in your body, the best and cheapest way is to get a hair mineral analysis done. This will also tell you the minerals that you are defficient or have in excess in your body. A hair analysis will also identify any excess halides -- bromine, fluorine and chlorine -- in you body and is quite useful in this respect.

Having taken borax for a while now(nearly 18 months), I have never had intestinal problems caused by this supplement. I take borax several times a month -- I take borax in water for four days and then take at least 3 days off a week. Borax is the ultimate fungal killer, balances the hormones and works well with magnesium to regulate calcium in your bone and body tissues.

Similarly, with iodine, I have never had a problem. In fact, it is quite well known that your salivary glands, stomach, prostate and the mucus glands in you nose, throat, lungs and intestines all contain and secrete iodine with mucus for protection against the bad viruses and bacteria in you body and this greatly aids your immune system in doing its job, so you can regard iodine as very body-friendly.

Bill, Are you using a full glass of water for the 6-10 drops of sodium thiosulfate ? Since my solution is in 30% concentration how many drops should I add ? Taken several times per month ? would once a week be sufficient ?

Then, I guess both the acv/bs or lemon/bs help with weight loss which is one benefit I don't need. (Being already thin) I thought is was the vinegar that facilitates this but i guess both remedies do this. Maybe it's a result of having the bicarbs put the body in more balance with markers?

I'm going to buy some mag chloride flakes to make the oil (skin application), but can the oil be taken orally too.

Do any of the alkalizing remedies or borax (1 liter), and Iodine remove the good flora in the GI too ?
(need for probiotics later)

Thanks Again, Joe

Bill:

The aquarium bottle that I found is broken down with following ingredients and %. Will this be ok to use and how would i need to mix to get to 10% solution ? Thanks again Joe :)

Sodium Thiosulfate 30.2%
EDTA Tetrasodium salt 9.8%

Hi Joe...I also obtain my bottles of sodium thiosulfate from an aquatics shop and although they don't say so on the labels, they are usually always 10% strength. And I wouldn't worry too much about this, because sodium thiosulfate is regularly used in much heavier dosages via IV for cancer chemo patients, where the chemo -- which usually contains dangerous lead and mercury to kill the cancer -- is buffered out of the body with the sodium thiosulfate after the chemotherapy.

The point is that we are only using drops of sodium thiosulfate here, but in chemo they use much larger amounts. I usually use 6-10 drops in my drinking water several times a month -- because getting rid of heavy metals and chlorine poisons from our food and water is a continual ongoing battle which will never end.

I also take iodine not only for health, but also to flush out dangerous halides -- like bromine and fluorine -- from my body. Iodine also helps to rid your body of cadmium, mercury and lead as well which makes iodine a very worthwhile and essential supplement.

Bill, below is data from Ted.

...The drinking water will therefore constantly reduce the toxins but there is another kind of toxins that H2O2 might not be able to neutralized and it can be switched over once a month or twice a month, only one or two day with the sodium thiosulfate drops. Which is 10% sodium thiosulfate, 10 drops per liter of water. It tends to neutralize other types of toxins. Initial taking of this may have a laxative effect, more like detoxification, thereafter no more problems.

I located a sodium thiosulfate bottle for aquarium usage. Is this always in a 10% solution or do I have to dilute it more to get there? The company does not tell specifics with %. Thank You for any help : Joe

Agree on the very underrated danger of chlorinated water, whether used for showers, cooking, or drinking.

Hot showers are especially damaging due to the large amounts of chlorinated steam absorbed directly via the lungs.

There is a small book out recently published which details the health damage caused by chronic exposure:
September 2008
'Coronaries Cholesterol Chlorine' book title
Joseph M. Price M.D. Author

Hi Debra from Brisbane, I have found a water ager at my friends house and all the name title it has is 'water ager cn, and it is the only one that contains sodium thiosulphate. It also smells like sulphur.(rotton eggs). It is a basically blue label with fishes on it.

I have contacted other companies that do not list their ingredients and asked them for the contents list and very few have sodium thiosulphate in them or maybe as low as 7 per cent, this one is primarily sodium thiosulphate.

My friend probably purchased it in a pet shop on the southside of Brisbane but it is made in Granville NSW.

Hope this helps.

Hi Debra...try buying the thiosulfate from an aquatic shop that sells fish, fishtanks and supporting goods. I bought my thiosulfate from an aquatic shop.

Sodium thiosulphate is even used in modern medicine today. For example, in chemo for cancer, sodium thiosulfate is regularly used as an IV buffer to flush out all the dangerous heavy metals that are used after cancer chemotherapy -- and used in much larger amounts than the dosages advised on this site. Drinking green tea three times a day would also help to flush out heavy metals or just eat cilantro (chinese parsely, coreander leaf) in salads 3 times a week would also work.

These would all be good remedies to start with against your fibromyalgia problems. Might also be a good idea to flush out all the bad halides from your body as well -- including the likes of fluorine, bromine and chlorine. Taking iodine(Lugol's) internally or foot-painting with iodine using Lugol's or simple tincture of iodine(I do this) is the other way of taking iodine by transdermal absorbtion through skin. Iodine also chelates mercury and lead out of your body and will also act to strengthen and support your immune system.

where do you get sodium thiosulfate in Australia?

Tried a few pool shops, looked on the net, sodium thiosulfate in Australia not easy to get. Will it really help get all this metal out of me? Will that finally help with the fibromyalgia pain. Does calcified arteries cause pain?

I see the sodium thiosulfate online with the name Pentahydrate next to it. Is this the same thing? If someone has a name brand that is at the pet store could you please email it to me?

Hi Haris, thanks for responding. I just recently noticed. I failed miserably in chemistry and it would be impossible for me to mix anything. How do you make you ST? I would be more content if I had a name to go with. I know Limassol is quite advanced in many ways and you can find most items. The only result I got was from a picture development site. I guess I will try the other stuff that Ted recommends like ACV and baking soda. I heard this afternoon on a health show that eczema and psoriasis is a complete shut down of the immune system, where circulation is affected and being deficient in fish oils and B complex. I believe that Ted has the best explanation. A fungal infection with a possibility of mite infestation and an acid predisposition.

You can usually buy Sodium Thiosulfate from swimming pool stores. You can definitely purchase it from Aquatic Eco-Systems....just do a Google search

Patricia, you will not get it from pet stores because they will not sell any other useless dechlorinator. You will get it from pharmacies. Also search on the internet and find how to make a solution to last you for years.

WARNING!

Well.. I went to petsmart looking for it.. The products weren't even labeled with the ingredients. I looked up one from the product site and the pdf it had about it made it seem horrible I wrote a letter to petsmart about it. You can get vapor damage and this that and the other thing from it. I'm not sure if i'm even going to try this now any more info?

Where does someone buy sodium thiosulfate? I went to all pet stores in my area and they don't know what I am talking about. Is there any other name that it is known.

Sodium thiosulfate is a common dechlorinator used to remove chlorine from drinking water. It is also a well known antidote for cyanide poisoning where the sodium thiosulfate reacts with cyanide to form sodium thiocyanate.

Some people who take too much apricot pits (cancer treatment) have a weak form of cyanide poisoning and found it helpful to add the sodium thiosulfate drops to reduced its side effect when they used the apricot pits, which is high in vitamin B17 or sometimes take apple seeds also somewhat high B17 to treat themselves of cancer or other immunity problems.

They have reported to me that the side effects were reduced from taking too much apricot pits, and caused them to be to nauseated, but when sodium thiosulfate drops are taken, no nausea effects from too much apricot pits is seen. Apparently the extra cyanide, if it were to exist in excess, reacted with sodium thiosulfate to form sodium thiocyanate, where the body can get rid of them quickly, but I also suspect that the sodium thiocyanate may have some antiviral, anti-cancer properties, perhaps only a tiny amount from eating apricot pits and the thiosulfate reduced effect, but its reacted components may have the same properties nonetheless. I would therefore imagine that the thiocyanate is less toxic than the apricot pits but also reduces the side effects by allowing the body to rid of them easier.

For me I used sodium thiosulfate to get rid of certain heavy metals, and accumulation of oxidative chemicals in the liver, as the sodium thiosulfate is a good reducing agent (reduces free radicals), but it is also a laxative in some respects, at least only initially in detoxification.

Most people are not aware that sodium thiosulfate is a common dechlorinator used in fish tanks, drinking water and swimming pool water, and sometimes a low amount of can be found in natural hot springs water, but they do have trace sodium sulfide too, which is why it can used to treat skin problems and some to bathe in it to relieved them of skin problems, rheumatism, although indirectly.

In other cases I used s.t. to help with sleep, as the reducing agent, especially the thiosulfate form of reducing agents helps with the sleep.

A thiosulfate form can form a weak sulfide compound which is also a component that works synergistically with the body's available nitrites to help to small extent anyway in controlling blood pressure or extend its effect for some people who take nitroglycerine tablets to treat both heart problems and high blood pressure. The effect is seen to last longer.

In my personal observation a bicarbonate formula, in alkaline form mixed with a very tiny amount of sodium nitrites works the same way based on my experiment as both the nitrogylcerine and the sodium nitrite degrades to nitric oxide in presence of organic acids. Interestingly, if the body were already suffering the acidosis conditions from lack of bicarbonates, the nitric oxide, which is the major component in controlling the body's blood pressure, does not degrade, and is more effective in killing of microbes, where its waste product, and the microbe itself are rich in organic acid. The sodium nitrite, produced by the body's own glial cells located in the brain, would degrade to nitric oxide, burning the acid forming bacteria, viruses and other microbes, much like burning them alive.

The sodium thiosulfate is also used as a photographic fixer, known as "Hypo" to prevent the chemicals of photgraphs from further getting dark and fix the pictures, much like a preservative, from preventing the pictures to be developed from further chemical oxidation.

I have also used it in the past to help sleep as well as to help concentration in event of ADHD, children's hyperactivity, and temper tantrums, and have worked remarkably well especially when a child of hyperactivity, is used to treat glutamine (amino acid) to help detoxify ammonia, and helped with brain development, is used in combination with sodium thiosulfate to reduced the resultant temporary hyperactivity that resulted from glutamine use. When those are used in combination, I have noted to cause a child to improve in leaps and bounds, which can be used for ADHD, hyperactivity, autism, and even emotional disturbances. For me, I also used s.t. as an anti-depressant and anxiety problems as well. At least for me anyway, the sodium thiosulfate has wide use, because of its unique properties as a reductant agent, it reduces free radicals, and reduces the liver accumulating actions of oxidative chemicals, where it is most dramatic as a treatment for cyanide poisoning. Still its everyday use is seen in fish aquariums and a dechlorinator for both drinking water and in use of swimming pools. In my opinion, people who used public bath cause their body to accumulate excess chlorine, the people who sells chlorine knows how much a human body uptake chlorine, which is quite a bit, but also does damages to the body. As a result, some people, like me for example, might after exposure to too much chlorinated water, will use the sodium thiosulfate solution to rinse by body of excess chlorine and perhaps some drops of sodium thiosulfate taken internally. Chickens and livestocks cannot use chlorinated water to chickens and pigs, as chlorinated water causes stunting of growth in pigs and chickens. At least in the case of chickens drinking water chlorinated in the farm, the biopsy of chicken were shown to have heart disease, and perhaps this line of chlorinated water used can be extended to human use as well. Of course human water, with chlorine and fluorine uses, is quite toxic to animals, and it is part of the many reasons why humans get sick. I imagine that the sodium thiosulfate to have much more wider use in the distant future and I have only begin to touch only just a small part of this, and not just its ability to remove heavy metals, chlorine, toxic compounds, excess cyanide, its anti-anxiety, anti-depressant effect, promotes sleep, is a laxative, used as a skin problems such as eczmea, and many other applications, I simply can't remember. There was one case of a child who reportedly got fat from swimming in a chlorinated water too long (for about a month) as the oxidative effect of chlorine tend to do that, and well at least help reduce those effect and at the very least, reduce being bloated, as the sodium thiosulfate would react with the excess blood chlorine to form a simple trace amounts of saline solution in very minute amounts instead of a more toxic chlorine.

The sodium thiosulfate is also used as a common remedy to reduce the side effects which causes deafness in some people from chemotherapy. But in my opinion, the free radicals also generated during x ray therapies, such as CAT scans can reduced such side effects just the same. I had a friend of mine who got a terrible headaches after getting her teeth x-rayed and took both vitamin C and sodium thiosulfate. Those two things stopped the headaches (and hopefully the radiation damages to her brain) the same day. It's probably the antioxidant effects from both the vitamin C and the sodium thiosulfate.

All this information I am telling is really old information (about 30+ years ago) as I found this out while doing experiments in U.S. high school. Nevertheless, with the trend in dumbing down of U.S. schools, I doubt any high school student today who studied chemistry would be aware of this as they are just too busy cramming for exams instead of doing experiments and make small discoveries for themselves. It was about the same time I think that Bill Gates was also playing computer programming at his own high school, which might be a monopoly program simulation, before becoming the world's largest software house.

I found the sodium thiosulfate at the pet shop 4 oz. $4.99
