I think it was run by an external pump before Iwaki wmd rxt 40 or rx40 not sure of the model though...
I run a pair of quiet one 6000's on my 300, but as stated previously, I built my overflows and drains around these pumps. Best to know what your overflow can handle before hand.
measure your overflow pipe size and check it against this calculator http://reefcentral.com/index.php/drainoverflow-size-calc it will give you pipe size needed based on desired flow volume. so if you want 1000gph through you overflow you need 10+ inches of teeth (barr aquatics) and a 1.3" (upsize to 1.5") pipe.
^^ use the linear overflow part of the equation as a rough guide though, as it mostly applies to surface skimming on a salt/reef system. The depth and width of your teeth will have an effect as well. On my 300 I'm supposed to have 36" of overflow for 2400gph. I actually only have about 26-28" on mine but due to the depth of the teeth my system could handle 5000 gph with no problem.
For fresh water, the depth of water being skimmed isn't as important as the drains ability to handle the flow, and if you run a full siphon drain(Herbie, bean) you'll handle ALOT more flow

so the same overflow box and piping will flow more fresh water that it will salt water? cool, didn't know that. do you know why?
very true about siphon drains doing more than typical overflows, that's because with a siphon the pipe is full of water and there is "pressure" on the flow, with typical overflow the pipe is not full and there is no "pressure". slurping noise is caused when a pipe starts to siphon and is sucking air.....
It doesn't flow more or less, but for a reef system it isn't desirable to have a deep layer of water falling into the overflow box. Surface skimming is better with a very thin layer of water, just the very surface..... kind of like they do on a coast to coast overflow.
As for the plumbing size, at full siphon(no air in the line) the drain can handle a much greater flow, but you really need to use a secondary drain as a backup in case the main line were to get clogged. That's your insurance against a flood. Herbie uses 2 drains and Bean uses 3.
Interestingly enough, on Beananimals page he shows using 1" bulkheads with 1 1/2" drain lines moving over 2000 gph with LOTS of headroom. So, it really depends on how you plumb your drains, as well as the size used.
