So I just picked up a 450 Gallon acrylic a few weeks back and I'm looking to make something totally amazing with it. I've been toying around with using dual acrylic sumps under each of the overflow boxes and turning them into refugi's and have each of them spill off into a central utility sump. I'm thinking that I want to make the doors on each side of the stand both front and back, left and right look like shadow boxes thus allowing me to stock some non reef specific animals in the fugi's. But honestly I'm also looking for idea's for really cool stuff to do in such a large aquarium. The aquarium is 10'x2½'x2½', with dual 9"x9" overflow's dead center left and right. Looking forward to hearing / seeing some of you all's ideas! Cheers!
