recommendation on return pump(s) -

[debbythefowler]

Hey folks,



I just finished an up-grade from a 220 'standard' tank to a custom made (Coast to Coast), professionally installed (NYAquariumservice.net) 180. I need a bit of help please.

Since i am old/old school, I run 2xMag 7s as return pumps from the sump. I've always had issues with heat and I run a chiller (which is 14 years old and still going strong)

I've been told that Sicce pumps generate much less heat than these old mags. Does anyone have any actual scientific tests to back this claim up? I'm also wondering if I upgrade the chiller from the current one, will that help? My sump holds 40 gallons, So I've effectively reduced my total water by 18%, plus I've increased my surface area (72" x 30" vs 72" x24")

any real scientific information?? I know many of you guys are pretty nerdy....

very nice, have you considered external pumps [less heat transfer]
just curious, if it was installed why didnt they recommend/install a pump?

 

[debbythefowler]

Ed, I didn't ask the install service to recommend anything. I had them break down and remove the existing tank, install and repopulate the new one.
Interestingly, years ago I had my tank running on external pumps. When I switched to submersible pumps, I had to put a heater on the tank for the first time. All that said, these were/are old pumps.

The mag pumps burn a lot of watts. That is where the heat is coming from. There are a lot of options with much lower wattage. Dc pumps seem to be lowest in wattage with comparable flow.

Debby, what is your room temp? 2 mag 7 should not be heating the tank too much.

personally i love the dart pump, low watt and amp and almost dead silent

 

[NYreefNoob]

mag pumps will add around 5-8 degree's in temp

I dont have any scientific facts - but I do have experience. I am using the Sicce in my 95 wave. Plenty of power and extremely quiet. I use one on the reactors and one as a return pump. I would buy them again. On my larger system I use external Reeflo's. Gold Hybrid - run cold and pretty quiet for an external pump.

Sicce Syncra HF Pumps the rolls Royce of pumps nothing better, lower heat and just simply the best!

Debby,
Have you looked into the DC submersible pumps?

I love my Sicce pump, and have also heard great things about Eheim pumps as well. I think either would be an upgrade from 2 mag 7's. An interesting note is that you can adjust the flow on the Sicce with a dial.
