As suggested, I got bunch of small blue leg hermit crabs to increase my CUC count. As soon as they are in the tank, many of them get on the hair algae right a way. I love them so far! :D
hehe... no, I'll see how this army of hermit doing first. It's funny seeing they all move as a unit at the moment. A big group of them marching though some LR mowing down the lawn. :D
