Well, things didn't work out. Planet Aquarium messed up the tank design, and put two overflows. The stand was built correctly with one overflow cutout, on the left, as specified, but, the right side of the stand was designed to be a dry compartment, so, no overflow was to be used there. Tank arrived with overflows on both sides. What little look I got at the tank itself, the silicone work looked shoddy. They also left the back of the stand open, where I specified I wanted it closed. Back on the truck to Texas, for another six weeks for another tank to be built. Sigh.
I'm also appalled by the lightweight build of the stand. My 120 gallon's stand probably weighs 3 times as much, is made of double laminated 3/4" oak plywood (so 1.5" thick on all sides), has five double laminated 3/4" (1.5" total thickness each) joists running from side to side (on both the bottom and the top of the stand), and is ROCK SOLID LEVEL and no twisting occurs when lateral pressure is put on it.
This stand, which is supporting a tank that is twice the size is only made of 3/4" ply with three to four 2x4 braces put in there randomly to give support. It's not level and rocks on the floor (the floor is 100% level as checked with a six foot level by me yesterday before delivery) requiring the use of shims, and, if I stand on top if it, and sway back and forth, the stand sways along with me. I can only imagine the same would occur if a wave is being generated inside the tank via Vortechs. I am sure this is because they did NOT close the back of the stand (combined with what I think is really substandard material thickness and bracing).
