Chlorine is unstable in hot tub temperature water.
QuoteChlorine is unstable in hot tub temperature water.Not entirely correct. Sodium hypochlorite becomes unstable and begins to loose its effectiveness at 120 F. At hot tub temps it works just as well as at pool temps.
Steve,Yes I am religious about adding 2 teaspoons of dichlor daily. I normally shock with about 16 teaspoons of dichlor, but occasionally use MPS. A month ago I was having problems with getting 0 FC levels just 15 minutes after daily dichlor so I refilled the tub and used SwirlAway. I again had this problem a week ago and shocked with MPS and also 20 teaspoons of dichlor within a 24 hour period. I was able to get the dichlor to read per my above post, but it is always back to 0 within 8 hours. My water will get just a little cloudy after a week, but using something like Clean & Clear always gets it back to sparkling clean. I am just concerned that my tub is not totally sanitary and don't know what else to do. I'm looking for suggestions.
guys,Vinny, I can't remember now, do you use MPS at all? You might try shocking with some MPS. That might oxidize out whatever is causing your cloudiness. Steve
