I have a new pool, 4 months old. Hayward T15 swg. I cannot keep the FC levels up despite running the cell at 95% for 12 hours a day for the past month straight.
CYA is 55. Ph has been at 7.4 for months and I have added zero acid. TA is 80. Salt is 2900. I have suspected that I have a bad salt cell since I can’t get the levels up and my ph doesn’t rise (I am told swg systems raise it). If I add some Chloroboost or liquid chlorine it will raise but fall back down after a day or so.
I contacted my builder about it and he says he can’t see anything wrong with it and thus checked for nitrates. He says they are 7ppb and claims this is why I can’t keep FC levels up.
I have done a lot of googling and get mixed results about whether nitrates affect FC and what levels are bad if so.
The pool is cloudy now and there are hints of algae starting. Anyone have an opinion on the nitrates? I’m still not convinced my swg is working up to par.
