Would there be a problem using calcium hypochlorite for sanitizing and shocking a hot tub. Â I understand the pH issues. Â Pros and cons?
BYW Â Tony, Â My 2007 Optima is really nice. Â I couldn't be happier. Â I noticed you had an optima also...any regrets?
Lithium is sold in the states! Â (SEABOARD INDUSTRIES). Â Lithium is an alkaline based shock so no harm done to heaters and seals.
CA is good in a pool when inbetween 25-30 ppm. Â When that level reaches above 100 the difference between your total chlorine and free chlorine will be wide. Â Your pool may demand the chlorine or even be green and cloudy but the CA level is so high the chlorine stays locked. Â The only way to free up some chlorine would be to do a water exchange I believe. Â The store I purchased my hot tub from tought me this. Â I have been using lythium hypochlorite since 1988 the second year I owned my 1st coleman spa. Â I also use it for my pool instead of those damn slo dissolving tabs that go into the chlorinator. Â It works brilliantly for the pool too. Â I don't find myself ajusting the PH as often as well. Â Calcium hypochlorite (HTH) cheap as hell at cotsco's would be ok with a cement pool to a certain point.
