I'm looking more for a reliable brand not the actual pump model etc. I've been doing a bit of research in preparation for hopefully setting up a DIY sump for a 300 gal tank. From what I've found so far I'd prefer to go with one of the new variable speed DC style pumps. So far I've found the Waveline DC, Diablo DC, SpeedWave DC, and Jebao DC pumps (ordered from most expensive to least expensive) but what I'm not finding much of is reviews. Does anyone have experience with these pumps either from personal use or know of someone who has one that can help me choose a pump
brand?

I'd also like any info you can give about power draw when run at less than max output. for example a Jebao DC-6000 has a max flow of 1585 gph and 40W whereas the Jebao DC-12000 has a max flow of 3170 gph at 84 watts, if I was to purchase the DC-12000 and run it at 50% would the power draw be 50% of max or less?

Thanks
 
I have used Danner Supreme Mag-Drive return pumps. Great quality and they are pretty quiet. They have many models to choose from depending on your needs.

The OP is looking at direct current (DC) pumps. Mag-Drives as well as most household appliances and electronics run off of alternating current (AC). I have no experience using DC, all my pumps are lagunas which are widely regarded as the most efficient submersible AC pump.

To the OP, why choose DC? I gather that it is easier to control speed of motor to control flow.

I looked into the Laguna submersible pumps and they didn't seem to be anywhere close to the efficency of the dc pumps when comparing for max gph flow. Most of the posts I've read on here regarding sump filtration recommend anywhere from 5 to 10 times turnover. So for a 300 gal tank I'd want from 1500 to 3000 gph flow rating from the pump. Some this task will not be overstocked I'm leaning towards something closer to the 1500 to 2000 gph rating. Now please correct me if I'm wrong but to get a Laguna that flows 2000+ gph that would be the max flow 2000 $200 and uses around 100w. A dc pump with slightly higher Max flow only uses around 70w plus it has the 6 position variable speed controller, ability to be hooked up to an Apex controller (which I don't have but would like to some day) and when turned on the ramp up slowly instead of all at once like an AC pump.
I'm still new to this hobby and know I have a lot to learn. From what I've been able to research the DC pumps are the most efficient energy wise avaliable at this time. That's important because I don't need my wife telling me that last month's electric bill was as high as it was in the middle of summer and is only March. That could put a serious damper on my fish keeping.

I'd the Lagunas are better please recommend which one should I consider getting?
 
Do you have a converter from AC to DC? Or is it built into the pump? I have 3 lagunas, the two 2400(PT8258) use 82 watts each and the 4280 (PT8256) uses 160 watts. My tanks are around 5' tall with stand, giving me ~1800gph with each of the 2400s and ~3225gph with the 4280.
