I just prefer a more fasteners to the possibility of a shattered tank and water everywhere.
like I said, maybe it’s just me.

One way I have always built stands is to construct them with screws as you have but when finished and level I drill through the legs and bolt the horizontal members with a 5/16 or 3/8" carriage bolt. This provides more than adequate sheer strength at those points.
