I have used food grade h202 in my hot tube for many years. It works well.Replied By Trena (Virginia Beach, Va, United States) on 04/02/2010
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!Replied By Audra (Or) on 09/28/2020
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!
