So another newbie question. I converted this week to the BBB method and turned off my puck chlorinator. I got my Taylor K-2006 test kit and ran through the tests. FC and TC were no existent and CYA seemed to be off the charts for me. I wouldn't even get to the first line of the tester before the dot disappears. So I started to change out water to see if I could bring it down. I wasn't seeming to make any progress, so I took my water into Leslie, because maybe I was just testing wrong. They were able to get a reading for me of 70. Mind you, I tested once right before and got the same off the chart reading that I had been getting. So trying to it get down a bit more, assuming their reading was correct, I dumped another 25% of the pool. Now mind you, I have not been able to take my water back to Leslie's to get another test, but my reading is still showing off the charts. Otherwise, I have started to add bleach as my chlorinator. I test about 4 or so hours after adding and my chlorine levels seem to be in the 4 range. However, when I test the next morning I am back to nothing. So to my real question, is that normal? Do I have to go through about a half bottle or more of bleach a day or is my CYA level messing this up?
