I am looking for a skimmer for a 630 gallon DT plus probably another 3-400 in sump and such. I was looking at a euro-reef rc1000. But then I came across the ASM G-6 Protein Skimmer which is rated at 1200 gallons for a fraction of the cost. How much am I losing out on with the g-6? I am on a budget so I am buying alot of my stuff used or DIY. So if anyone has other skimmers to recommend or sell speak up.
