Ah, okay, forgot about the single-pass ones... but still... for $200? The DAS EX-1 will keep up with that thing. The large body diameter of the 200 doesnt mean a thing... its all about the air throughput and the contact time (interface, turbulence, whatever other terms you want to throw in... the EX-1 is still better). .

Yes. The older OTP3000 pumps were moddable performers. But they were revised, er, rather, retarded recently, and it seems nobody can get more than 20 scfh out of them. I dont think its just the needlewheel... as with modding, you would change that anyways. I think the pumps have lost some copper or something in the stator end. Either way, Im not wrong on this one Rich... look in the Octopus modding threads... I havent seen anyone having any luck with them since the 'revision'. That, and I have heard of alot of the OTP pumps are dying. No doubt... their power factors indicated they were a very poor design. They also tend to be loud.
So heck, a single, quiet, aquabee 2000/1, pulling about 23 watts (less wattage) can do 18scfh stock, and a couple have modded them into threadwheels for over 600lph, or over 21 scfh per pump.

Okay, so take a $200 skimmer, replace the pump for $100, and you get a $300 skimmer that does 800lph. That is do-able if you want to spend that much. By the time its all done, you have a $400 skimmer though (time, shipping). I suppose you could mod a 3700 though... and get 1000lph. But still... by the time its all done, they why not just spend the little bit more up front and get the DAS EX-2? 1000lph (or 1200+ modded), quiet, efficient, reliable, and a better skimmer design (recirc/ counter-current).
Another pump I would suggest over the Oceanrunner actually would be the Gen-X 4100. Its cheaper, and it can pull down 1000lph easily, if not more.

So far Euroreef is winning on the service end of things, they have already contacted me, verified shipping and the pump is on the way, due to arrive on Wednesday. Prompt service. Online Aquatics, the source of the AquaEuroUSA skimmer, emailed back that they won't have any to ship for two weeks. The DAS source hasn't replied yet but they did take my money!
