Sold that house in April and bought a new home in Massachusetts, with an older pool. Since reading TFP I've only used sticks in NJ when away from home for 1-2 weeks and primarily use only liquid 8.25% Chlorine bleach, baking soda and borax.
1st season problem showed 2500 ppm phosphates now down to 200.
I'll recheck CYA and raise the daily FC, thank you, I knew the shock level raised for high CYA but didnt know it was safe to run the high Cl all the time with the elevated CYA!
New pool is 26500gal vinyl and I just installed 244T hayward sand filter and new 2 hp superpump, waiting for the over the deck kit or enough courage to crack the slab for the pressure side return for a polaris 280.
