I'm looking at a couple of options for my tank.... drilling is not an option... Here is what I'm thinking
Refugium with lighting,sand,LR
Marineland overflow box that drains down into a "tank" for a refugium and sump, with light of course.
I'm looking at this for added quantity of water, and a place for pods
and macro (nutrient export)
any of these sound possible??? any other ideas???
