Re: Screws on top of aquarium stand
#2
I've not seen a stand like this before, so can't be sure whether it is designed for a specific/bespoke tank that has some sort of screw facility into it, or whether it's designed as markers with the tank fitting against/inside the rectangular perimeter screw holdings (eg so that the tank doesn't move slightly when it's initially filled up with water).
It certainly *won't* be ok to place the tank on top of the screws nor even on top of the holes if the screws had been removable as the tank would be severely compromised. What *might* work is a layer of polystyrene foam cut to the shape of the base of the tank, placed on top of the stand underneath the tank, with a fishtank/aquarium base mat on top of that, then the fishtank on top of that. The screws would presumably then make a natural dent on the underside of the polystyrene but wouldn't cause it to 'collapse' down at those points.
