In that photo, there seems to be some haze obscuring the pool cleaner. Is that a pic before or after you added 3 gal of muriatic acid?
For all that muriatic acid, a pH of 7.9-8.0 (post #16) seems quite high. That was a day after your pH tested 7.0 (post #1)?
Ok, we made it! Just to clarify, the pool was clear up until this last Tuesday. We had a big rain Monday night and when I woke up, the pool was super cloudy. I backwashed and rinsed, left the pump running all night, brushed the walls and tanning ledge and vacuumed nonstop, and added two gallons of muriatic acid Tuesday night. Wednesday morning, it was clear as a bell. Numbers were still a little skewed, but I’m sure that was because of the muriatic acid.
Wednesday night, it rained even harder, and the pool was cloudy again. Yesterday, my FC was ok, no CCs, TA was 170-180 and pH was around 8. CYA was around 30, but I had good chlorine.
I went home from work, added another gallon of muriatic acid and some cleaner. An hour later, my TA was 130, pH was around 7.2, FC was 10, no CCs, and I could tell a change in the clarity. This morning, after pump running and vacuuming all night, we have a clear pool.
It seems the major problem was dirt washing into the pool from around the patio. We are installing a French drain this afternoon to try to mitigate the problem, but the dirt seems to be the root of the cloudiness. Have not tested the levels this morning, but everything looks good for now.
