New member, but I've been reading on here for a few months. I have a fairly new gunite pool, opened in March, 2014. 22,000 gallons. Has an ozonator on it, for some reason. Ran with Ozone and low FC with trichlor pucks inline for a few months, until algae in June. Fought algae with powdered Chlorine until end of July, when I found this site. Noted that CYA was off the chart, so I did a partial drain and fill, and got CYA down to 100. Plan to go lower, but haven't done it yet. Anyway, Algae has been gone, and pool has been nice.
The problem now, is that I am having to add acid twice per week to keep PH in line. Of course, TA is now going down, and also CH has gone down. I put my current numbers below. I am concerned about adding this much acid. Only added once per month or so when using pucks. I know the pucks keep PH down, but just not sure why it continually goes up now? Is it still curing? Should I be concerned?
Any ideas would be appreciated. Thanks.
