I've been battling a black algae problem for about 2 weeks so wanted to get some advice and see if I'm on the right track. I started off with a SLAM and have been running the pump nonstop (other than to clean the filter). Brushing from out of the water 2 or 3 times a day with wire brush. Spots on steps near the surface are gone but still have a good amount in the deep end. I thinking I need to take a swim to brush those deeper spots.
