JOhn, I see no issue with hanging a remora on a sump, you just need to lengthen the tube between the pump and the skimmer itself. I think comparing the remora to other types of skimmers is apples to oranges, it works differently, and it works well. I have a remora pro w/ Mag 5 on it running on a 110 right now and it produces Filthy Nasty horrible stinky skimate. they are good skimmers. Couple things:
And this is just me:
I would buy a remora Pro with a Mag 3 on it instead of a standard remora, this gives you room to grow if you decide to break down and move up to a larger tank, it also gives you a 'buffer' of protection if something in your tank crashes, you have a more powerful skimmer that can help stabilize things. I ran one on my 30 with no ill effects for many months.
Second, I would agree, go with a sump and put a powerful return pump on it, like a Mag 12 or 18, and buy a couple SCWDS, plumb the return with a T, then hit the SCWDS on either side of the T, and run in your returns, there would be four, you would get your wave action for sure, but you would drop from 4 more power sources to feed to 1 (granted, the Mags probably eat a lot more) but you get my point.
Remora's rock, I am keeping mine until I buy a Deltec skimmer.
"Maybe in order to understand mankind, we have to look at the word itself: "Mankind". Basically, it's made up of two separate words - "mank" and "ind". What do these words mean ? It's a mystery, and that's why so is mankind." ~ Jack Handey
