I can agree with both of those, but if you have a bit more coin to spend, the H & S recirculating skimmers are VERY effecient. The LFS in my area that sells them has a H&S set upo next to a"same size" Euro-Reef, and it kicks the E/R's butt, by about 3 to 1 in skimmate production, and uses LESS electricity! Very nice skimmers, just a little bit more spendy.

These sell very well, so he has a hard time keeping them in stock, but he also has problems maintaining his website to current stock levels. That problem is supposed to be getting fixed in the near future. You have to call or e-mail for availability
