Thanks all - this is a great forum. Wish I found it before I trichor'd my CYA up to 120 and spent a ton of $ on algae killing products and phophate removers.
I am using a Taylor K1004 DPD test kit, and I got a false reading for PH for the first time yesterday a few hours after I added Bleach to my pool to bring up my FC, and then I added a pint of MA to bring down the PH
before I read this thread
Today, my readings are:
FC > 25
CYA 120
TA 100
PH 7.5
13,000 gal plaster inground pool.
My reagent is Taylor R-0014, should I trust the PH reading given my FC is > 25? (I used distilled water this time for my 1:4 dilluted test sample)
I'll be getting my pool replastered in the next few months, so I'm holding off draining my pool water and want to try to keep the algae away, but not ruin any pool equipment!
