I need to whip up a stand for an acrylic 240. 2 by 8 footprint. I have a 6 foot sump Ide like to use with it. If I wanted to put it under the stand could I leave a 6 foot window in the front of the stand for sump access? If so would 2 2 by 8s be enough to support the tank or would I need a third in there to compensate for this 6 foot tunnel? Would like your opinions!!
