Hey folks, dealing with some heavy algae growth on the tiles above the water line (in the grout lines). I’ve tried to raise the water line and SLAM with no success. Wire brushes will break up the grout. Any chemical ideas? Otherwise it’s scrubbing w my hands and a nylon brush which I’m far too lazy to do.

Ha. That was going to be my initial suggestion - a toothbrush or something similar. You know, you could just make a time of it. A spray bottle, brush, then hop-in for your daily pool routine and hit those areas while you're in there.
