Does anyone know a safe way to remove algae from a ball sponge? Our orange sponge has been in the tank for two weeks and today I see there is a small amount of algae (brown, not hair) on it. It is also on some of the yellow polyps that emerge from it to feed. Someone suggested that I use a soft toothbrush to remove it. I don't want to cause any damage, or worse yet, kill it. :help:
