I have a custom made stand (not built by me) that came with my 75 Gallon Fish Tank. I like that the height of it was made for an eye view of the tank instead of having to bend down to see the fish clearly. My issue with it is that I can't put a tank on the bottom. I have my 10 Gallon ADF tank on the bottom, but the stand technically wasn't built to have a big fish tank on the bottom (no bottom braces, cabinets or anything, just open space). I was researching double stands and I was wondering if this (below website) would really hold up well for two 75 Gallons or if it's not worth it?
