Im looking to buy a hang on refugium. I was looking at the <span style="color: #0000ff;">CPR Aquafuge 2 Refugium w/ Protein Skimmer 19.25 </span><span style="color: black;">for my 55 gallon. Does anyone own one of those and can let me now how good they are. I was more interested in the skimmer. I own a cpr bak pak and i was wondering if that skimmer on the aquafuge would be equal or better then the cpr bak pak i own now. thanks</span>
