I have an Aquapod 24 and have had an hair algae problem for some time. I use RO water on water changes and while its not growing out of control It is still a pain in the butt. I have changed out one of the sponges for floss in the back in efforts to rid my tank of nitrates. It worked. I have three fish, a clown, a sixline wrasse, and a rainford goby, and two em. crabs. The goby ignores it. Any suggestions of what would eat it that isn't too large for my tank.
