We finally got our kit in the mail and I sat down and measured the dirty details for our 9500 gallon above-ground pool, which are:
FC = 0 (unsurprisingly, we've been just periodically adding some packets the previous owners left to keep it from being green)
pH = 7.2
TA = 50
CH = test turned purple even with the pre-adding 0012 trick. Should I dilute with tap water and try it again? Or is "red/pink" more purple than I'm anticipating and I should persist and add more reagent? I didn't want to waste it so I quit fairly quickly.
CYA = 0 (sample was clear as glass alas)
We were hoping to do the whole SLAM thing this weekend, but I'm not sure which other things need to be fixed first. Bringing the CYA up will mean we lose less chlorine, so I'm guessing we should do that first? Do we need to do it a full day before, or is a couple hours fine?
The TA is a bit low, but should I adjust that after? I'm really not sure what to do about the CH at all--with a vinyl above-ground pool this seems less of an urgent issue, or am I misunderstanding?
The pool is very very cloudy but not terribly dirty looking, though the bottom could be covered in algae for all we can see it right now. It was open and only partly drained all winter, and the previous owners used those pucks for chlorine, so I'm a bit surprised CYA is so low! It got "tested" by my MIL's dog last weekend, and as far as I know she's still alive, so it's not the swamp it once was.
Thanks for any help you can provide!
