If anyone could post some pics of their stands..for a 110gal tall.. I would greatly appreciate it. I have a iron stand..but just don't know if it will hold .
You only need 1 center brace if you change your 2x4 beam from laying on its face to its side. You have MUCH more strength this way. The above design is nice and overkill, except the beam is the wrong way. You will get much more strength out of the crossbeam going on its side.
I have noticed that most diy stands are built with the horizontal board sitting up and not flat like mine. I just decided to do mine different
One reason I did it this way (flat) is because any slight bowing of the horizontal 2x4 would not be an issue (however, I'm sure the weight of the tank would probably take care of any bowing anyway)
Like chesterthehero mentioned...I put the "overkill" of vertical board supports so there won't be any issues concerning the top board.
