First - THANK YOU for having this forum. I've learned a lot and had a wonderful first year with an inexpensive Intex pool, last summer. It was their bottom-line metal frame pool and, at the end of the year, we realized they are not built to have covers on them during the winter. So, we ended up leaving it up with water in it and no cover. We've added chlorine a few times and run the pump, but don't know where to start the real process. The water was greenish, but adding chlorine and running the pump cleared it up almost completely. We need to clean out dust, worms, dirt on bottom and brush as we add chemicals, but it's looking pretty good believe it or not!
Do we start with lowering the pH, or start the same way as last year with Dichlor for a few days? Here is what we've got in numbers:
pH - off the chart, above 8.2 (last year it was consistently high - about 7.8 - but the pool was beautiful)
CYA - below 20 (could still see dot with full tube)
T/A - maybe about 150
Didn't test chlorine - figured that's useless.
Although I've never used it (bought before finding this forum), I have "pH minus" on hand. It is Sodium Bisulfate.
I cannot find Dichlor. It could be that I ordered it online, last year. Just don't remember. Could find again, I'm sure.
If I can't find Dichlor, would this work for the CYA part? It's hth brand, "stabilizer & conditioner" = active ingred. 96% cyanuric acid, inert 4% undisclosed.
Thanks very, very much.
