I'm new to pools and this forum, but look forward to all help on this subject.
I followed directions on the site and got rid of my algae problem. Water looked beautiful afterward.
Then I had an issue with very high CYA. I again followed the directions and drained off about 25% and refilled.
Since then, I continue to have issues with chlorine loss. I switched to liquid chlorine as recommended, but I'm now going through large amounts (at least 1 gal/week). We do experience high day time temps (90+) and significant direct sun.
Here are my pool data:
6700 gallon vinyl liner pool
TA = 140
CYA = 60-70
CH = 350
pH = 7.5
TC = 3.0 - this drops to <0.5 within 12-18 hours
Any helpful suggestions are appreciated.
