I wanted to get some snails to keep algae under control but none of my LFS have the astrea, trochus,cerith or nassarius snails only turbo. The last place I stopped had a 5 in. sea hare.He suggested to get that and it would take care of all algae problems.Right now algae is not real bad and thought it might starve.He said it would even eat BLACK algae ! What is that from? So should I get the hare now or maybe later or stick with the snails. Did get 4 turbos.
