our development has a 55,000 gallon steel pool painted with a rubber based paint . we have a 100 cartridge filter system with a Raypak 720 heater - we filled the pool and add the appropriate amount of calcium chloride and sodium bicarbonate to get the PH and hardness and alkalinity to the appropriate levels.
as soon as we turn the heater on a white precipitate begins to appear on the bottom and sides of the pool - ( I believe it is calcium) and as soon as people begin to swim the pool clouds up
we keep the temperature ate about 84 F
any ideas ?
