Oh, a pool without algae is a dream at this point. After the liner was installed, the pool guys put our drop in steps back in (they weren't supposed to because the sand bags had not been cleaned yet, although the steps had. We had a liner failure along with a massive pool leak in the return line and our pool was a frog hole for about two months before the work started.

When the weather warmed up the algae took off. We got it knocked down and then it started growing in the open area under the steps again. When I brushed, a green tide went all over the pool.. We had another clog in a line last week, and the pool guy told us it is yellow algae. So it is back to the drawing board for us.

The bottom of the pool was clean - not now. Back to the drawing board - kill algae, remove dead algae, etc.
