I wasn't going to get any but after doing some research, I'm going for it. Had to do some research since I wasn't able to find much. I did round my numbers up a little because I'm not going to be a scientist on it.
Size:
DC6000 - 6.2"x3.5"x4.7"
DC9000/12000 - 7"x3.5"x4.7"
Output:
DC6000 - 1,600 gph
DC9000 - 2,400 gph
DC12000 - 3,200 gph
Power Consumption:
DC6000 - 40w
DC9000 - 70w
DC12000 - 85w
Most tank return output are about 4-5" so keep that in mind when selecting a pump. Originally I was going to go with the DC6000 but after a 4ft head loss, it puts out about 900gph and that's without taking into consideration of my reactors and stuff. So the DC9000 fits the bill for me, it puts out 800gph more then I need but it can be controlled to dial it down. I just realized I might be able to tee this off to my chiller as well. This is replacing my Eheim 1262 which currently uses 80w and puts out 900gph at zero head.
