did you make that double stack stand or buy it?
I bought it from the LFS that I bought my first 55 gallon from. There whole store was set up with those. I liked it and they had a spare one and sold it to me. For about a year, I just had a tank on the bottom while I waited to put a tank on top.
What is also cool, I filled that first tank with mbuna that were all bought with store credit from selling convicts that I had raised to be about the size of a nickel from a different LFS.
I have thought about building another myself, it is just 2 X 4's that have been routed in the front. It is screwed together, it might also be glued. It is very sturdy.
If I ever take tank pics again, I will do some close ups.
