Above ground round 28' Doughboy. Opened up the pool this spring, cleaned things up, got the levels where they should be and it was ok for a week or so then water got cloudy. Could not get ahead of it as algee kept appearing on the sides and a little on the bottom. Had water tested and we needed to add shock and 17 lbs alkalinity plus. It was ok for a while then went bad again quickly. Decided to check behind and inside stair cavity. Bingo, algee city.
Moved stairs out and below them was a ton of algee as well as rock bags and inside stair cavity.
We did not take the stairs out this winter, and every two weeks I scooped leaves and dumped in two bags of shock then swept the bottom to assure shock desolved.
How does one keep the algee from building up under and inside stairs?
