Internal return pumps besides mag series

jscarlata · 08/14/2011, 11:17 PM

What other internal return pumps are recommended besides the mag series, specifically the 9.5, that produce less heat? My tank is kind of warm and i think it's because I'm running a mag7 on my skimmer AND a mag 9.5 on the return. Drilling my sump will be a royal pain, so I prefer to stay with internal, 3/4" output and around the same flow/headpressure as the 9.5. I suppose I could replace both, the 7's shielding on the cable is a little worn anyways, and I can easy repurpose the 9.5 for my mixing station...

Specs
Deep blue 90, custom sump/fuge, tek elite 8bulb. Not sure on the volume of the sump, it's 28x15x15 with a 10" water height.

Quiet ones 4000 and up. I have one on my system and its really quiet makes mag drives sound like freight trains.

I've used several Mag series pumps and I've always been very happy with them. At the concensus of this forum I went with the Eheim 1262, and so far I'm happy with the quieter operation, and less heat production. My last concern will be craftsmanship and longevity.....which time will tell.

Thanks everyone. So far both pumps are quiet as can be, but my tank temp is higher than it should be with only T5's and little to no heater going. I'll get a clip on fan today for the sump area, and will finish transferring all my corals over from a temp 30g so I can hookup my Controller and keep a better eye on things.

Eheim 1262 runs cooler than the Mag7, and the WaterBlaster pumps are quite efficient (cool running) also.

My temp with lights going Skimmer and return pump stays around 77 78 towards the end of the light cycle. How much are those pumps?

I have been around many neglected systems from people who called for aquarium service and many of them have been held together by string, duct tape and often an eheim return pump that has been running for years unchecked through power outs and gunk buildup.

Thanks!
I finished moving my corals from my temp tank to my 90 last night, in the process i decided to shut the skimmer down because I have little bioload right now and I wanted to see what would happen to temps. Low and behold the temps stabilized back to 79 overnight. I'm wondering if my older mag7, bought used, is running hotter than the 9.5, sure seems like it so far. I do recall using the 7 to mix water in a 32g brute and not needing a heater ever... Maybe I just need to swap the 7...

Your sump is about 25 gallons + or - 1 gallon.
