Here is my wifes 55 future Seahorse tank and my 40b. I'm using the 40 until I find something bigger to go in its place. I built both stands myself. The stand for the 55is designed for a 55. The 40 stand is designed for a 55 or larger. It is a lot longer than needed because I wanted storage space underneath. Yesterday I built the temp light suspension so I could hang a Coralife 150w Metal halide. The 55 has a 4' 4x54w Power Compact light. The 40 has the 150w MH. The only thing in the tanks so far is sand, dry rock, and 1 piece of live rock each. As soon as I can figure out how to post pictures off of my phone I will post some.
