We just had a massive rain that added about 4" of water to the pool. I drained it about 7" and then refilled a couple inches. Everything seemed fine. I then left town for a week and came back to super cloudy water.
The salt meter on my automation equipment says that my salt is low and isn't operating. Salt was at 3200 before I left town. The small drain and refill shouldn't have dropped it that much. I have salt test strips, but I don't trust them at all. The readings aren't consistent.
FC was at 0 yesterday, so I added a bottle of bleach and kept the pump running. After a few hours, FC was back at 0. I did that again, same thing. Something is consuming chlorine in huge quantities.
CYA has dropped from 70-ish to about 25.
Measured pH this morning - see below. It's a ruby red color. Doesn't match the colors at all. FC is still at 0.

When this happened last time, someone suggested that the wind might have blown in bacteria that overwhelmed the FC and ate the CYA, which would create ammonia. I have ammonia strips that aren't registering anything. The cure last time was about 6 bottles of bleach - I'm about to make a Home Depot run.
So......any ideas? This is the third time I've had this happen in this house and it's really annoying.
