Even though I keep my parameters in check, I always find a little algae on the floor of my pool? the waters crystal clear when I take off my solar cover but the floor isnt?
I sweep it and it's gone until a few days later. I had this problem last year too and I tried slamming the pool and even passed the overnight test, same as this year?
I run my filter 4 hours every day on a timer and add my bleach every day.
Also, no matter how much borate I add ( I use the calculator and add the recommended amount) I cannot get my ph up.
I have tried 3 times in the last week. I even tried a different test kit with the same results.
