I sold my 75 gallon tank since I upgraded and the guy did not want the stand and sump so I decided to make a frag tank to fit the stand. It holds about 30 gallons. I made two matching racks that hold 121 frags each and one that holds 16 of the 2" frag disks. I got some of the neon green acrylic to try out and looks pretty sweet. Wont put water in it till summer so I got time for some new lights.
