How to get rid of green hair algae that is growing on my live rocks? I can't do crabs because it's an aggressive tank. I test my water about once a week and everything checks fine.
I have the same problem too. To much hair alge, but I add iron because I have live plants in there for my seahorses. I would like to know if there is a small fish up to 2 inches that eats hair alge? Anyone?
