Hi, This information may be on your site somewhere but I haven't accessed it yet. I was wondering if you could tell me of a chemical free solution to keeping a hot tub. The therapeutic value of hydrotheray is nullified by the chlorine/bromide we have to use. I do have an ultraviolet light. Do you recommend food grade hydrogen peroxide?

Thank you

I have used food grade h202 in my hot tube for many years. It works well.

My husband and I no longer want to use chlorine and bromine and all the other toxic chemicals in our hot tub either. I've done a lot of research and hunting to find natural alternatives. I have found 3. We are trying the first one right now. I can't give any brand names or anything but I can tell you it is a colloidal silver. Emptied and cleaned the hot tub taking out all parts possible and cleaned with a toothbrush. Filled up the hot tub with tap water using a carbon filter. All I did was dump the 16oz bottle of colloidal silver and it's been sparkling clean for a month now. We use our hot tub every night. But here's the kicker. We do shower every time before we get in the tub. Bought 35% H2O2 and when I empty the hot tub after 3 months....I will try this method but I won't use the carbon filter to fill the hot tub with this method. The 3rd one I will try will be another natural product. All I do is dump one bottle in every 3 months and that is it. So far the colloidal silver product is awesome! No smell and we are so clean!

Thanks for the info. We are new to having a hot tub and searching for the healthiest way too! Can you update us on what the 3rd thing was and which was best. How much H202 did you use and how often?

Thanks so much!

Hi Ron,

How do you determine the amount. How often do you add and do you use anything else?

We just bought a house with one, but have no experience and would prefer to keep it healthy without chlorine and chemicals if possible. Thanks for any advice!

I've heard about H2O2 in hot tubs but what is the dose rate per litre and H2O2% used. Thanks in advance.

H2O2 works really well in pools and hot tubs, I did it for years. No chlorine smell! Wonderful water.

I suggest you call around to see who does the Baquacil system among your local pool stores. The one I used did classes on teaching you how to do it.

Pool chemical suppliers will be able to tell you everything you need to know based on the volume of water in your tub. They usually use 35% H2O2.
