Since my last post I drained and refilled about a foot of water from my pool in hopes of lowering the CYA some. I won't know until my test kit arrives. I got the PH up to about 7.2 and the TA is down to about 110. Since Monday I've poured 17 gallons into the pool. Checked the reading this afternoon and its only about 1.0. I added 3 more gallons a few hours ago. When I first add the bleach the chlorine level goes up pretty high (my test kit only goes to 3.0, so I'm guessing somewhere between 6.0 and 8.0), then in a few hours it drops back to between 1-3. Is there some reason it keeps dropping or do I just have to keep pouring in the bleach?
