how long do you think you will know if a home made stand wont hold.i have a closet took the sliding doors off laid a few 2x4 on the floor then a few up rights with 5 2x4s going across with 3/4 ply wood on top . its a 100 gal tank with sump under it been up and runing 6 months about now.i tend to wonder at times if i should drain it add a 2ed sheet of ply wood and some more 2x4s .its sorta built in to the walls to a few screws
