Hi all. What's he best way to clear out brown algae. It's over my fake plants. It's starting to make my water cloudy. After a water change it clears slightly but returns in a few days. Anything I can clean my decor with to get rid of it? Anything I can add to my water to help combat this? The brown algae came from a lump of wood I had in my tank it has now been removed but algae doesn't seem to slow up. Thank you all!
