So when I picked up my 40 gallon breeder tank, I went ahead and picked up one of these- . It's not available online, but in store they have a model specifically for the 40 gallon breeder tank. Problem I am having is that once put together (and I've tried reversing a couple parts already to no effect) is that when I sit the tank on top it wobbles a bit. It's almost like two legs diagonally across from each other are higher and make it pivot. It's not drastic, I'd say probably less then a centimeter. But it's noticeable and I'm worried a fully filled tank on that would cause enough flex to cause issues/stress on the glass and joints. I've already returned the first one and the second one has the same issue. Any thoughts or ideas? I thought about just maybe shimming one corner but wasn't sure if that would work out well and probably wouldn't look the best. I considered making my own, but that's complicated by not exactly having the set up to make one as I live in an apartment at the moment. Could probably pull something off but not at the top of my list.
