This is really the first full season of owning our house with a pool. I opened it to a swamp this year, did the SLAM, got the water clear and since then, Ive used 4-5 of the Trichlor pucks in the chlorine generator and a couple pound packs of shock for chlorine, but mainly to get some CYA in the water as well since I had none.
Over the past month that the pool has been open, post SLAM, Ive noticed a trend I cant put my finger on.
Chemistry wise:
TA: 80
CH: 200
CYA:50 (I keep this a little higher because the pool is on the N-NE side of the house and is 95% sun exposed during the day)
FC: 2-4 (Ive found adding about 1/2 gal of 10% bleach every other day is about right)
pH is whats bothering me. I use pH Down instead of MA, and twice within the past month, Ive had the pH slowly but steadily drift from 7.2-7.3 to 7.8+. Usually a dose of pH Down fixes the issue, but Im trying to understand why. The only major change Ive made lately is adding a pump timer that runs the pump 6 hours a day, usually from 10pm to 4am.
Thoughts?
