Just turned on the hoses to refill my pool after draining about 80 - 85% of the water to deal with high CYA and CH, and also to attack some stains while I had things drained.
My question is, should I hit the pool with some chlorine now, while it is just starting to fill, or wait a bit ('til morning) then test and add some then?
Any advice?
For what it's worth, the water when I started draining:
FC 13.5
CC 0
pH 7.4 (tested using 1:1 dilution with distilled water due to high FC - I know this is approximate)
TA 110
CH 450
CYA 150 (tested using 1:1 dilution with distilled water - many tests - this is the average)
Temp 79
I did some testing of my fill (tap) water a few days ago in preparation for this. I had some trouble with FC - maybe it's because of what they use to chlorinate here in FL?
Anyway, here's what I got:
FC 1.2
CC 1
pH 8
TA 200
CH 210
I think I drained about 85 - 90% of my pool water (total volume = 12000 gal) , so just using some ratios, I expect I would end up with the following once it's refilled:
FC 3.3 (not sure about this or CC due to uncertainty around my tap water measurements)
CC 0.9
pH 7.9
TA 187
CH 245
CYA 21.3
Any thoughts here on whether I need to add chlorine right away? Amazingly it looks like I'll need to add some CYA and I know I'll have a battle on my hands to reduce TA and get the pH in check. Any pointers or advice much appreciated!
