6 Minutes in that chlorine chemical bath and your skin has absorbed as much chlorine that is equivalent 10 glasses of tap water. Plus all the related dry skin issues. No thanks especially with all that work of testing testing and more testing. Here is what I have finally decided works for us. ours is an indoor 7 person tub, it has a salt water generator (now disconnected) Tried the Bromine thing "nah" to many variables - testing is continuas etc. Will not use chlorine "we all know that its a carcinogen lets admit it" Finally was told by a hot tub "specialist" to use Lithium, a very high chlorine base. However it will test zero within 1 hour of putting it into your tub 1tbs per day (after bathing) this we were told would be our solution. This s--- actually drove our ph onto the crazy scale we couldn't keep up with the sudden variations. Also because it is indoors we have a fan running from the side vent to try to keep the temp. down as quite often it gets up to 103 - 104. Now we have been looking into the peroxide solution for quite a while, but all the "experts" that had helped me so far kept claiming how bad it was going to be and blah blah blah. We took the plunge last fall (6 months ago) I can tell everyone that this stuff is amazing. 1. I have not done a chemical analysis or home test since. 2. I add 1 litre per week (a cost of $7.00) and rinse out the filter. 3. The water is absolutely sparkling 4. Our skin is soooo soft My wife is amazed 5. We are in it EVERY night 6. No other chemicals like stabilizer, bubble burst, ph up, down. 7. Actual product name is Peroxysan. Do not let the "experts tell you this is bad" try it,
