Hi there. I'm in need of some help. I live in Central Texas and recently purchased a home with an above-ground vinyl pool It is about 12,000 gallons. I drained about 80% of the water a couple weeks back because the CYA was very high. Now, it's about a 30. I have been SLAMming the pool with liquid bleach to try to get everything kosher. Problem is, I can't maintain my Free Chlorine level. I have been testing and slamming twice a day the past week. Last night (9:45pm), after I added bleach, I was at a 13.0. This morning (9:00am), I was at a 7.5. My understanding is that it shouldn't really change overnight?
I have no idea what to do. The stairs haven't been in there for several days (so any possible algae in there isn't affecting it). The PH level is fine. I just took some water to PetSmart and they said I have "little to no ammonia" with their test strips. I don't know what else to try!
What do I do?? TIA
