I am planning out a closed loop for a 60g cube (24" all around). I have never implemented one before but have been doing some research lately and am definitely open to some help or direction. I am planning to use eductors/penductors on the outputs to increase flow. I have a spare Queit one 3000 on hand but am not sure if this pump would be sufficient. So far, I have figured loop piping will be 1" with at least 4 (though possibly 6) outputs with an educator/penductor on each output. From what I have gathered, the use of the E/P's will increase flow rate by 4-5x... So am I mistaken in thinking I could achieve a flow rate within this display of ~3,000gph with the above application? My other questions at this point are: what size outputs/E or P's do you recommend? How many?... Should I stick with the 4 or bump to 6? The stocking plan will be a mixed reef, and I realize part or most of the design will be experimental but I am reaching out to those will closed loop experience for some pointers. Thanks.

Not big enough of a pump for your plans. The eductors will help but not as much as you are thinking. The pump is a 780 gph pump, you will not have true head loss, but will have friction loss with any bends in the plumbing. Fortunately they are a strong pump but the low gph is not really adequate to benefit from the eductors. Long ago I tried the same with a Mag 7, the flow was dismal to say the least, and that was with 1-1/2" plumbing. Eductors work better when the flow is increased, low flow and eductors do not work as well.
I had a feeling that would be the case... For my application what gph rating for the pump should I be shooting for? Any suggestions on a particular pump? And I am not opposed to an external, the quiet one is just what I have on hand... Though noise is an issue since the tank is in the living room. Need something quiet and of course efficiency is key.
Thanks.
Thanks.
I would probably be looking at either the water blaster pumps or the Askol's, the Askol 2400 would rock for a closed loop as would the water blaster. The Askol would probably be quieter though. Or you could also go with the traditional external pumps, most of which have become very energy efficient the past few years.
