Hi there is my first post here and I have become very interested in bimacs. I have read most of the articles thus far. One thing that I have a question on is filtration. I assume LR is better than a wet/dry. What do you guys use for filtration? Would a wet/dry filter, a hang on tank refugium, plus about 30 LBS of LR be good for a bimac in a 75 gallon tank?
