Hello all, well I can't begin to tell everyone how glad I am to get off the pool store treadmill! I've been chasing a greenish and/or cloudy pool all summer and when I stumbled across "CYA" last week and performed the test with my Taylor test kit my CYA was at 100!!! Of course this explains why my pool had a bad chlorine habit! Funny the pool store didn't mention CYA when they happily sold me pucks for my feeder...
Approximately 25,000 gallon in ground, pebbletec surface.
Anyway I drained the pool this weekend, a light acid wash and she's refilling as I type. A few questions:
1) I know the first thing to do is test my water to establish a baseline then get my CYA straight. I plan to slowly get the level up over a week or two so I'm around 40 (or, would 50 be better?) I'm in Las Vegas and the pool gets sun from sunrise until around 5:00pm when the house shades the pool.
2) Once the CYA is up does it matter which level I adjust next?. I assume Chlorine then PH, Alkalinity, Calcium one at a time but is the order in which each is adjusted (for those that require adjustment) critical?
3) Due to the price/concentration at the local pool store I plan to use Liquid Chlorine. I understand from reading here on the forum that Liquid Chlorine and common household Bleach are the same thing but, is any compelling reason to use one over the other aside from price? Are there any impurities/additives added to pool store chlorine which should be avoided?
