I have a 40 gallon saltwater aquarium,In it is two blue damsels and a yellow tang, conditions are perfect.I am thinking of upgrading to a reef. But I can get a light but I want to know if I can run a reef off of a three stage bio wheel filter, a protein skimmer, and 40 or more pounds of live rock.Because I heard that live rock is a better filter than a wet/dry.So I could have a natural filter. Any comments or answers are greatly appreciated. And the reccomendation of any product!
