looking for a solid RP that would be able to handle this task WITHOUT being a energy hog and only want something that is NOT going to put heat into the water... quiet is also a + (obviously)...
ideas?
ideas?
what return pumps best for 1,000g tank

Maybe look at getting some redundancy and going with two pumps so that if one fails, you have flow continuing. Take a look at: http://www.rlss.ca/#!dc-pump/vstc3=dc10000
Affordable DC pump with speed controls.

Good rule of thumb is if the pump is in the water, its the similar as a heater the same wattage as the pump worth of heat going into the tank, if its an external pump, you'll still add heat simply because of the internal heat generated but hopefully not as much as an internal pump.
Although with a 1000g tank I doubt the pump will put a dent in the temperature change, in fact that's less wattage you'll use on heaters, where as with the external pump you'll essentially be "wasting" the heat to the environment.

So what's the deal with DC pumps? What about them that makes them so special/desirable for a return pump? This one definitely is cheap from what I've seen (Abyzz comes to mind as definitely being the antithesis of cheap

Well, I have to admit that I've only seen and do not own one of these pumps. I believe that the prescribed benefit is low wattage usage for quite a lot of water flow. Also, they are generally controllable in that you can vary the flow of water out of the pump.
As a general rule, the DC pumps that have been available to us have been very robust as there appears to be more technology that goes into perfecting them.

I've got the Deltec E-Flow 16. It's amazingly good.
Lifts effortlessly the amount of water I want from my basement sump room...

does the Deltec show wattage or flow rate on the controller??

One of the bigger values to the DC pumps besides being able to vary the speed, is that the pumps are much more efficient at their use of power.
Where, the standard AC pump works at about 50% efficiency, that means half your power is lost to heat. But with the DC pumps the efficiency is 'supposedly' much greater. Some pumps claim as much as over 90% efficiency, which means more water moves with a lot less heat being produced.

Im running a waveline dc5000 on my 180 and love it so far, super quiet, only drawing 32watts on the setting im using, temp in tank down .5 degrees, can be used in sump or externial, has soft start and feed mode that shuts pump down for 10min and then turns it back on. Not sure of long term quality issues, but seems very well built and heavy duty, north american production.
