Is it possible that bleach can push pH up? I've read the pool school materials and used the calculator, and don't see any indications that it should, but I can't think of why else my pool suddenly has much higher pH
Measurements (yesterday -> today)
FCL 0.5 -> 4.0
CC 0 -> 0
PH 7.5 -> 7.9
TA 60 -> 60
CH 150 -> (not measured) (will add more hardness soon)
CYA (last measured at 24 a few days ago, then added 64oz CYA powder)
The only chemical I added between the two readings was about 48oz of WalMart Great Value brand 8% bleach. Well that plus the CYA from a few days ago is probably still dissolving but I'd expect that to push ph down not up?
So my questions are:
1) could this be from bleach?
2) if so will it also fall again as the fcl is consumed?
3) if #2 is true is the idea that I'd start to think about the fcl ranges I want to be in, and how much bleach that means I'll be adding, and therefore how much MA I have to add so that even with the rise I'm still at acceptable ph?
Thanks!
