Anyone have any tips on how to clean algae off a small zoa frag? It's not super bad. Not effecting growth. Just looks ******. It's small amounts of a redish hair algae growing in between the polyps. I can't quite grab it with my sausage fingers. Was thinking tweezers but that seems to be a pain in the butt. Any chance you can run a soft toothbrush over them without hurting them?
