Thinking of building a sump for my 65 hex. Ideads needed!!

[The Grizz]

Hey all fellow reefer's. I was sitting here in my living room looking at my 65 Hex and don't like the way I can see the hang on skimmer, intake and outtake of the canister filter.

I have seen overflow boxes that a person can get & I could use my hang on skimmer in the sump but don't really know how big a sump I would need or return pump for that matter & how I get proper filtering ( Mechanical, Bio & Chem.)

I am upgrading soon to my 155 gal Bow and moving everything from my 2 - 65 gal tanks to it. Then re-doing the 65 hex for the seahorse my wife wants so it doesn't have to have a strong flow. The return pump flow I would more then likely have near the bottom as to circulate the water.

Any idea's would help greatly. I do have a few empty tanks around that i could use, also could very easily build something custom.

Thanks in advance to all who reply.
