That is what I did Monday night after we were done swimming. And the pool was clear the next morning. I have less than a half of a bucket of Triclor left to use so they don't go to waste. But now that i know it raises my CYA I will use them less often now. Just enough to keep my levels where they are now. Then I will switch to bleach. I am going to call around and see where the best deal is on bleach or if anyone can help me find a place I live in NE Atlanta area.
