Just bought a 300 Gallon fish tank. The Dimensions are (LWH)8ftx2ftx2.5ft. The glass is 1 1/2 cm thick. The Tank seems very solid, but looking at other tanks this size, they have center support glass on the top. This one does not. It is just four walls and a bottom. I'm going to fill it up in my garage and see how it does,but wondering if this is fine before I do? Thanks for the help. Oh another thing, The plastic frame around it is taken off but I have all the pieces, I was going to put them back on but I'm planning on making my own stand and it would cover the bottom anyways, so is the frame necessary? Looks like just decoration to me...Thanks for the help again guys!
