D/c return pump recommendation

[charliethetuna88]

Im thinking about trying out a d/c controlable return pump for my system .i dont have much head pressure or distance to go with my return line .this is my first d/c pump so i figured i would ask and see what is everyones using and which to stay away from ..i have a panworld now thats been with me for many years but im starting to hear bearing noise

try giving your pump an overnight vinegar bath

Have been using 2 jebao dc return pumps for a year now. Quiet, cool, fully adjustable, no complaints at all

Wait a few months. Apex will be releasing the COR. Will come in 1500gph and 2000gph. Here's a link from macna

I ha e a 300 gallon marineland tank with the 2 corner overflows .i wonder what the max flow rate would be for them

What size pipe you have coming out of the bottom of the tank on each overflow?
You want the return pump to return around 1500 gph, with head height figured in. More is not better here.
300 gal x 5 = 1500 gph

Can tell you that even if the overflow is one inch on each of the 2 overflows, that can be done.
1" pipe can handle 800-850 gph if air is going down the same pipe, more if air is going down a separate pipe. As with a herbie type overflow.
800-850 gph x 2 = 1600 -1700

Save energy? idk, could check the wattage of comparable gph pumps. DC pumps certainly run cooler, and for the most part quieter.

Charlie Coralvue makes some nice DC pumps that can be run externally or internally

Charlie if you want to go dc i would go with ecotech or wait for either the apex or sicce.
I will be upgrading soon and will go with one of these.
