Powerhead for a 20x20x16 cube

[ReefDreams]

Hello guys,

I was wondering what could be good for the waterflow in my cube, my sump is powered by a Mag-5,

The tank is about 27g, the sump is exactly the same size as the tank but will hold less water (water line at 10")

With roughly 300-400 gph already in a system that has about 40g of water, what do you think I should put ?

Ideally I want a minimal heat output, and an energy efficient pump

Thanks

I've got 2 koralia 2's in my 30 gallon frag and that seems like enough flow. It doesn't generate much heat and power consumption is very low.

If you have the cash, Vortech MP10 or some Tunze nanostreams.

I would def use 1 or 2 mp10s.... this will create the best flow in my opinion

It really depends on what you want to keep.
I'd look at a couple Tunze 6025's.
These can be picked up used all the time in the used equipment for sale forum.
If you have a large buget then maybe a vortec.
