vamptrev;3480537; said:i would put legs under the 3 middle supports going from side to side. i have the same design on a 4'x4' tank and it sags. i used 2x6 on my other 4'x4' and it worked great
all your legs look very good!
the three middle supports are 1/4" higher than the rest of the stand. i figured it would sag so i put them up slightly higer and then i put a 8'X4' layer of 1"thick hard foam insulation and a 3/4" sheet of plywood. if it still sags ill jack it up with a car jack and add the supports. id rather not have them if i could get away with not having them.
