Sump Question

[dylanjs]

Hi Reefers,
I have a question about a sump I want to build...really, it's a question about sumps in general.

Does a sump have to be below the tank entirely? What I mean is: is it OK to have a sump below the water-line, but next to the tank?

I live in NYC, so I don't have room for a stand, but I can make room for a sump-like thing next to the tank to hold the skimmer, fuge, doser and carbon. So, it would be below the water-line, but on the same level as the tank.

I would use two overflow boxes to carry the water over and return it with pump, as if it were a "traditional sump.

Any thoughts?

it will work

Should work but why two overflow boxes?

Two overflows for more even coverage. Not worth it?

how big is the display tank? if its 90 or under stick with one overflow box

 

[dylanjs]

The display is 55 gallons

one over flow is fine
