I will be honest.
I didn't close the pool properly. Maybe I was curious just how well the BBB method would work.
I had a green swamp. I started testing and dumping bleach, brushing, changing out filters, etc. CYA wasn't even registering, so I put a bunch in a sock of pantyhose and checked it a week later, still not registering. (By this time, I had found a part on Pool School I had missed, that if CYA wasn't at proper levels, it wasn't safe for the pool to bring it to shock level, so I was keeping the green at bay by keeping FC around 4). I put more CYA in (and I don't have a great way to measure, so I use the Pool Calculator, and kind of guesstimate). Another week, and CYA is STILL not even registering with the test kit.
So. Any suggestions? Am I missing something?
Oh, and pH is high too, 8.5. Muriatic acid brings that down, but where do I find this? Should I even worry about that at this point with the nonexistent CYA and green swamp?
