The algae covers the rocks almost entirely, so it would be a massive pain to have to pluck and scrub each rock. I would like some options besides having to do this. I have a bunch of snails, but they do not even touch the stuff. Some of it is an inch long. Would a sea hare touch hair algae this long? I heard leaving the lights off the tank for a few days would kill it off as well, is this true?
