Last year, I switched to TFP and had to do a 75% drain and refill to bring my CYA level down to normal. Overall, had a great 1st year with TFP. Could not believe how easy it was with only bleach!
Just opened the pool and got these initial results:
FC 4
CC 0
PH 7.2
TA 110
CH 180
CYA 35
PoolMath says all I need to add is borax to raise PH. I assumed FC would be 0 and I would have some CC. Is it normal to open a pool with ready to swim readings? Do I still need to SLAM? Water is clear and sparkling. This just seems way too easy - I must be missing something...
