My CYA levels are also very high and unfortunately, due to the water shortage and the draught here in California, I cannot dump half of the water in the pool right now. Even after adding 16 gallons of 10% Chlorine over the last 2 weeks, my free chlorine quickly drops to 0 every morning. The pool math calculator says I would need 30 gallons of 12% chlorine to get the FC up to a reasonable level(25,000 gal pool and spa). I have been also adding Calcium Hypochlorite to keep the algae away.
If I do ever get some FC to read after nightfall, I would assume that with water exchange and backwashing, as my CYA goes down, the bound up chlorine will be released somewhat (except for the amount lost during backwashing of course) due to the now lower concentrations of CYA. Is this true?
I will avoid ever using a stabilized chlorine product in the future (Leslie's ChloroBrite).
What is the power consumption rate of a SWG cell system? This may be cheaper than liquid chlorine even after the expense of the system, salt and running costs!
