Hi there, first time poster and new pool owner in Texas.
We we went on vacation just after closing on the new house and came home to a green pool. I don't know enough about the pool to put it all in my signature, but here's what we think: 25k gallon, plaster, DE filter, pentair pump. Previous owner was using tablets, which I'm assuming is the cause of the high CYA (see below).
Brought a sample to Leslie's this morning and here are the results:
FC - 0
TC - 0
CH - 220
CYA - 110
TA - 110
pH - 7.6
After reading on these forums, I know we need to SLAM. We are draining some of the water to get the CYA down and bought 20 gallons of 8.25% bleach. We ordered the TF-100 kit, but while we are waiting for it to arrive, what would your advice be to do? I'd hate to see it get worse.
