I have to constently scrub the alge off my saltwater aquarium. I realy want to get an alge product but I have live rock in the aquarium. That has the coraline alge on it that I do not want to get rid of. Would a UV steralizer work? Any solutions? The reason there is alge on my aquarium is beacause i have a powerful light on the tank. The water is ok in clarity and I kep up with my WCs I just have alge. By the way it is a 30 gallon aquarium with 2 common clowns and a six line wrass and they are all juveniles and they get along great and as you know live rock. Any solutions? Thanks...
