Folks, my apologies for not posting this build from the start. I'm doing an identical Frag Tank on the right side next month so will post step by step on that one. Here's the background. My reefandfins coral & Fish business was running out of space and I didn't like the cluttered look of just adding more 45g tanks so I decided to build my own tanks. I have limited space and wanted form, function and aesthetics as well. This is what I came up with: two plywood 8' x 3' frag tanks framing in a mangrove display refugium with a touch tank for grandkids which could hold my starfish, hermits etc. The top tier on both sides over the Frag racks will hold acrylic partition tanks for my breeding pairs of fish. Which tanks are connected to what, has not yet been decided as I need to figure out best nutrient levels and quarantine concerns. It's a work in progress with I'm sure quite a few more roadblocks to encounter but pretty happy with the progress so far.
