 Is a protein skimmer necessary?
I'm in the process of building/purchasing a hang on refugium for my 55 gal tank. I'm not sure if i'm going to build it or buy it. My question is their seems to be two types of refugium one with a skimmer and one without. For example CPR Aquafuge. currently my tank has a small wet/dry filter built on the canonpy that i want to replace with the hang-on refugium. So my question is a skimmer required? I've read some post saying that its not. Also is CPR a good brand for refugiums? Is their other alternatives out their?
Thanks |
