I have two large peices of lava-rock in my tank stacked together to make a little cave where my fish like to hang out for some privacy.
I've notice LOTS of brown algae growing on the rocks. My plecostomus does a very good job of cleaning everything in the tank except the lava rocks. He will eat a lot of algae off the surface of the rocks, but the rocks are very pourous and he can't get into all of the little holes.
Will lots of algae on the rocks cause any problems for the quality of the water?
Is it advisable to leave the rocks in the tank? It seems to create a never-ending food source for the plecostomus...
