A pal of mine has the issue of needing a serious skimmer for a 350 gallon. But his sump and plumbing is not easily modified. The simplest way of adding a very large skimmer would be to drop a feeder pump into his sump and sit a recirculation skimmer next to it. No experience with MRC recirculation skimmers, so input, or other similar skimmer ideas are very welcome.
