So for the last few weeks I've noticed rust looking debris on the bottom of pool sporadically throughout. Not sure if it algae as the water is clear. Brushes up easily but in a few days it's back again. I back washed today and there was a lot of greenish water in the glass piece. We have had in unseasonable hot summer. And I noticed chlorine dropping significantly after a day or two of adding liquid chlorine. I've tried to find the amount I need to slam the pool but can't seem to find it on the forum. I'm just nervous to slam because I already have some wrinkles in liner and really don't want to add to it. My test results are:
Fc: 13
Ph7.4
Cc: .5
Tc: 13.5
Calcium: 250
Ta: 130
Cya:60
Any help?
