Hi guys!
I have a question about CYA...
My original thread about the pool is here: my-giant-pond-is-almost-a-real-pool-and-some-questions-t15311.html
Initially (about a month ago), I added about 64 oz. of CYA (it's what I had on hand at the time). I put it in an old nylon and then put that inside a tube sock, and hung that in front of a return. It took more than a week for it to dissolve that way, about 10 days altogether. After doing that, and waiting a week to test the levels, my CYA tested at around 20 ppm. Last night, I finally added the rest of what was needed according to the pool calculator to get it up to around 40 ppm. However, I decided to skip the nylon stocking inside the tube sock, since most people said they just put it in a tube sock. Maybe I should've left the nylon stocking in there, too, because when I got up his morning, the tube sock was EMPTY. (I also think I may have inadvertently added a few ounces too much?) I really don't know what could have happened for it to have dissolved that quickly this time! I'm not seeing any undissolved substance in the pool, no clouds of anything anywhere. I turned the pump on high and put the vacuum in just in case, though, and have been running the vacuum for a couple of hours so far this afternoon. Everything seems to be working OK -- pump, skimmer, filter, etc.
I decided to test the CYA just because... I know I'm supposed to wait a week, but this is unusual, and I'm concerned. I tested the pH and FC, too.
FC: 5 (have been targeting for 5-6 range)
pH: 7.2 (was 7.5 prior to this)
CYA: 60
OK, so that seems high on the CYA, above the target level which was 40-50. This IS a sunbelt region, and the pool gets a lot of sun every day, but is this going to be too much? I'm a little freaked out about this. Is this going to cause problems? What should I do???
Thanks!
