I refilled my pool 5 weeks ago due to high CYA and started TFPC. I'm having trouble with my pH creeping up, and my FC drops faster than I had hoped.
This week was typical:
Last Saturday: pH 7.8, FC 2, TA 90, CYA 50, CH 230 -> added 1 gal muriatic acid, 1 gal 10% bleach
Next day: pH 7.4, FC 6.5 -> looks good
Today, 6 days later: pH 7.8, FC 2 -> ack!
This is typical, my pH creeps up ~0.4 units per week and FC drops by 4-5. :-(
My pool is 2/3 covered with floating sheets (it's a weird shape). Water temp is ~75 deg. I don't have any water features or anything that would aerate the pool. I'm starting to get light algae blooms, probably because my FC dips low at the end of the week.
I'm spending $10 per week on pool chemicals. Is there anything I can do to keep it balanced for longer? Why does my pH creep up?
Thank you,
James
