LARGE Sump ideas....

Only 2 baffles needed and lots of room for everything. You can add some egg crate or mesh to cover under the second baffle to keep small inverts and such from crawling into the return pump. I grow Prolifera and chaeto in mine, with lots of extra rubble and even a removable deep sand bed in a tupperware container (about 7" deep).

Hey Anthony! Any chance you have a pic...I can visualize it better that way.

AND...I think I may be leaning to a refugium as El Guappo suggested. It could be a very interesting place for kids and grownups alike to view crabs etc as suggested....
