Well i'm semi retired and i've had myself a custom build system of two starfire tanks. One is a 75 gallons display refugium that dumps by gravity into a 150 gallons Reef tank. Being partial to softies for their movement in the water column i had an external glass wavebox build as well for my 6 foot tank and so my tank will be mostly devoted to LPS, Softies and NPS as i've created a dark zone, with my sculptures.

I strongly beleive in a planed aquasculpture and waterflow to avoid dead spot. So my tank has a ceramic backwall 30% more porous than rocks and gives more grazing for the fish .I also have to put less rocks on the sand and gives the fish more room to swim. I can then put my sculptures and make it more interesting since its going to be there and in are face for a long time lol.

The Refugium houses a collection of Macroalgaes to help in a more natural filtration system its also a biotope for seahorses and something else.Both tanks are on 2"powder coated steel frame. I couldn't hide the black pipes between the system so i decided to make it part of a theme; a familiar Borg look , with green and blue lights gives it a dramatic flare with its green lit salt water corner drum ( warp core) lol. The back stair case are for the cats that were there before the tanks. My full build up at http://www.thereeftank.com/forums/f6/two-cats-and-two-tanks-build-up-meow-210457.html
