I have lowered my water level twice according to the pool math to get the CYA down. Switched over to liquod bleach for my chlorine. Brushed the pool daily and cleaned the DE filters twice during the process.
Everything seems to be spot on with the pool math calculator. Did the overnight chlorine testing but am still having algae form on the walls. Could I be dealing with something else? Going out now to brush down the pool while I wait for replies.
Thanks in advance.
