Almost like a table without the solid top. The top is made out of pine wood frame only under the tank’s frame so other way I can see from below the sand inside the tank. And I did build sides to it as well like you say to protect it from buckling sideways or forw/bacward. It seemed to me that there is no need for additional support under the tank between the posts except to make the stand like a big cabinet.
Just recently I realized as well that the beams under the floor are parallel with the tank and so there is some kind of swivel forward when stepping on the beams next to the tank. It is quite complex to find the right spot without having the tank next or in front of a window.
Thanks.
