OK i am probably going to get a new tank. its 48x18x17. i am wanting to build a stand for it but the way i am wanting to build it is with a ten gallon under it. i looked on garf and been reading a bit but i cant come up with the dimensions and i dont want to mess it up. i was wanting to go with cinder blocks but i live in an apt so i dunno if it would hold if it will i prob use blocks and paint them black. just wondering if anyone can help me come up with some dimensions, and should i use 2x4 or do i need to brace it somehow.
