Pentair 1 or 1.5 HP pump (new replaced in 07/2012)
Pleatco PCC60 Cartridge for Pentair Clean and Clear Plus 240 (new, replaced in 05/2013)
pool was built in 1960
cleaner: Polaris 280 (don't know how old, at least couple years, working condition)
Water test result: temperature between 65 and 90.
I believe TA is too high and free chlorine is too low based on what I learned from this site. The pool is in bright green.
My tenant was told by Leslie pool to use "green to clean" with super shock to bring it to normal.
According to the pool calculator, I am supposed to use Muriatic Acid to lower TA and then aerate to increase pH.
My question is what should I really do? We use 12% liquid chlorine, 68% Cal-hypo 1lb bag, 3 Inch Chlorine Tablets (occasionally), Chlorine-Free Pool Shock, 60+ Algaecide, and First Aid Pool.
