Here is a pic of one of my most favorite tanks that I ever put together.
In this pic you can't see the closed loop pump hanging on springs above the RDP Refugium.
In this pic you cannot see the corner overflow plates that were removed.
In this tank you can hardly see the overflow pipe and the Closed Loop piping.
In this tank you hardly see the legs suspending the reef off of the sand so Mr. Ray and Mr. Bat.
The return from the Refugium is an unfinished 1" Tee visible at top center.
In the pic, the simple RDP Refugium using a Rio 2500 for the return pump is visible.
There are no baffles because the floss bag and the Chaetomorpha keep the bubbles from reaching the Rio.
Unfortunately this tank no longer exists, but the Blue Spot Ribbontail Ray is swimming in Dion Richins tank underneath the suspended reef.
