Hi everyone. I have been reading this site all winter as we moved into a home with a pool in November (my first), and am pleased to say I haven't had any trouble with the pool so far, but it's only been open for a week, haha.
The pool is vinyl, has a SWG, and currently the water looks great. I've got all the equipment working properly and the water is clear (it was green when we opened, but cleared up nicely with SLAMing and has been great ever since. I think my test results are pretty good, I just want to confirm, because I'm not 100% sure of the CYA level since the water is cold (around 58 degrees.)
Most recent results are:
FC: 5 -- this is slowly coming down after SLAMing but it's taking a while. Finally sunny today, so this might help?
CC: 0.2 or less
CYA: I think this is between 30 - 40 ppm, quite low anyway but I am finally registering some after the addition of 2kg of stabilizer when we opened and filled it up (pool is ~ 24500 gallons). Prior to that I wasn't getting any cloudiness at all. I don't want to add any more in case it goes too high. PoolMath had me adding like 4 kg or more. My SWG has a sticker in it that says recommended level for CYA is 20-30 ppm "if required"??
TA: 100
CH: 125
pH: 7.5
If anyone could let me know if this sounds OK, that would be great. PoolMath keeps saying corrosion of plaster, but I'm not sure if that's a concern or not in a vinyl pool. I'm afraid to do anything to the pH since I believe I'm on the high side for TA???
Thanks in advance for your help!!
