insulation pad or not?

Just a quick opinion check....

Do I put an 1/2 inch piece of foam insulation between tank & stand or not?

Currently I have one cut so that it sits inside the bottom frame, and most of the weight will be off the outer rim of the tank in fact with the tank empty the bottom is 1/8 inch off the stand. Its a 46 gallon bowfront tank.

thanks

Not an opinion, but what is recommended by tank manufacturers.

Glass tanks should be supported along the edges. Look how a store bought stand looks that is made for a glass tank. You can use a thin strip, like weather stripping, around the bottom edge, but not foam under the entire bottom if your stand has a flat top.

Acrylic tanks should be placed on a flat surface with foam under the bottom. The flat surface of the bottom needs to be supported and the foam will help with any imperfections.

Just to strongly reiterate what cccapt said...

Do NOT put anything under a glass tank that keeps the weight off the edges. Foam as you describe seriously runs the risk of breaking the tank. I have a 46g bowfront also, and the plastic rim sits directly on the top of the flat top stand. I leveled the stand itself between the floor and the stand.

Just to reiterate or clear up, there is no need to support a glass tank that has a built-in frame (usually plastic along the top and bottom dimensions) around it and is usually not recommended by many manufacturers. If the glass tank does not have a built frame (custom tanks), same for acrylic, then a foam pad can be used; however, I would only add .25 to .5 at the very most.

You should definitely place foam between the tank's plastic frame and the stand. The foam, if the compression density is correct, will eliminate any twisting force caused by a uneven stand or a floor that sags a bit over time. The twisting force is one of the main causes of sudden tank breakage or leaks. To help understand the force; imagine placing a quarter under one corner of your tank and filling it with water. The silicon seams will be under a tremendous shear force that can suddenly cause the corner joint to fail.

The poster wasn't placing the pad under the entire tank (including the rim) they were placing it under the inside of the rim trying take the weight off the rim. The answer to that is a resounding NOT RECOMMENDED BY MANUFACTURER not to mention we have a real life example here of someone who recently did just that and cracked their tank.

Ziggy's tank did not crack because it was on styrofoam.
