Ok, I'm starting to get some algae growth in my 37g that I've had running for over a year and a half. I know why it's growing now. Recently I removed a sally lightfoot crab that had been in there since I started the tank. He/she was a monster. Easly over 4" from leg to leg. I got rid of it because I didn't want to have to worry about it killing my fish(it hadn't, but it was getting big). Now that he/she is gone, I'm seeing algae growth. I have some mexican turbos and some trochus snails in there, but they don't spend much time on the rockwork. What do you guys use for algae control? I'm tempted to get another sally since it did such a great job. Anything else?
