Skimmers with becketts require a ton of flow....and are very noisy....but, in my opinion, the best at skimming. That said, when I ran an MRC, I was using a MAG 24....i.e. 2400 gph. So if you wish to run this off a manifold, you'll need an enormous pump. As far as noise, not an issue if your sump is remotely located....like in your basement. If it's immediately below the tank, in the stand, be prepared for a bit of noise.
Plumbing is quite simple....pump water in and drain water (with valve) back into the sump. Here's one of my external MRC's.....clear tubing (towards the back) is incoming water, valve and white pipe is drain back into the sump.
And here's how it looks in the sump....closest pipe is water being pumped to the skimmer....1 1/2 " pipe right behind that is water returning to the sump.
