In my Malawi cichlid tank I current have a wall of ocean rock spanning from one end of the tank to the other. I'm really happy with the setup. The problem is I really like my rocks to be clean, I don't like brown and green algae growing on the rocks and have to remove different rocks every couple of weeks to clean and keep on top of it. I ve heard that a UV filter can stop algae growth do you think it's worth investing and does anybody use one.
