We just opened the pool.
Last year we struggled with high CYA (after buying the house) so we want it make it right this time.
I measured the water (using TF-100) and here are my results:
CYA 110 (initial reading was more than 100, so later I measured CYA for pool water mixed with tap water which was around 55)
FC = 4
CC = 0.5
CH = 100
TA = 110
We plan to drain at least half the water.
What should we do next? The pool store would like us to drop 6 lb of shock but I want to ask you, the experts.
Thanks in advance,
