Brand new pool, brand new pool owner.... I have read alot of the pool school. Thanks for all the info. Ordered TF-100 test kit. Here are my numbers. Water is clear.
FC - 7.0 (morning) Drops to 0 - .5 by afternoon
CC - 0
PH- 7.8 - 8.2
TA - 100
CH - 300
CYA - 0
Salt - 3380
I understand why the FC drops (low CYA).... my question is do I lower the PH before I raise CYA? How does CYA effect PH and/or TA?
How long after adding CYA to pool water is safe to swim? I dont know why the PB has never mentioned CYA. I have had them test the water for start up. After finding this site and reading noticed that they didnt test for CYA. Is this common practice for pool stores to ignore CYA?
Thanks again for the great site and info...
