This is my second summer with the TFP method. I have some scaling and high TA and wondering what suggestions are out there.
FC = 6
CC = .5
PH = 7.4
TA = 150
CYA = 50
CH = 175 (pool store hardness sample = 354)
I have a vinyl liner, so I thought the CH doesn't matter that much. However, I notice a 'whiteish' ring at the water line. In the past I added scale inhibitor under the pool store method. Should I add some of this to bring down my CH?
My TA is high from last summer (pre TFP!) when the pool store had me add an insane amount of sodium bicarb. I never have luck bringing down the TA - I drop ph and aerate without much change.
Any suggestions are appreciated!
