New to the forum and pretty new to pool ownership. We had pool service included for a few months and now that it's ended we decided to DIY. We went to a local pool store last week and they told us that our chlorine level was at zero and our PH was high. This was after a week of no pool service. They were only coming once a week so we assumed we only need to check it once a week. Oops. Anyway, the guy at the local store gave us GLB Granular which is 99% Sodium dichloroisocyanurate dehydrate and says 56% available chlorine. Also gave us some muriatic acid.
He told us to add 2.5 to 3 lbs of the the glb granular and I think 1.5 gallons of the muriatic acid(will have to double check with the husband). He said it would be safe to swim in within 45 minutes. Tested the water about 3 hours later and chlorine levels were crazy high. We started off with one of those water testers you find at lowes(Chlorox brand). PH was fine.
So next morning we went in to Leslie's instead and these were our results(last Sunday):
FAC 10(again, she said it was off the charts so it was probably higher?)
She had us add Chlorine neutralizer to bring levels down. Tested it a few hours later, Chlorine was still high, though it did go down noticeably. Haven't added anything else since then but we've been swimming and temps have been in the 100s. Oh, and we do have one of those little chlorine tablet floaters.
Went in this afternoon to have our water tested and these were this week's results:
Just got our TF-100 kit, so haven't had a chance to read up and use it yet. From what I understand, high CYA is not a good thing? Will we have to replace water? The water is clear. Also, what would make the CYA go up like that within a week? Or could it be that testing at Leslie's is inconsistent? I'm going to try to get a test in tomorrow morning to see if there is a difference but I'm hoping for some advice and maybe some reassurance that we are ok to swim in our pool while we get this figured out?
Sorry, I know this is long, but not sure what info will be the most helpful.
