setting new tank on base

I've read about putting a thin sheet of insulation under tanks to help level and fill small differences between the tank and the stand. Is this a good idea?
Also, should my tank (125g rr) be sitting on a solid piece of plywood? Of course the bottom of the tank glass is a bit raised from the base trim, so right now the outer edge of it is all that is contacting the stand. Do I need to place plywood that is cut to support the bottom glass?

insulation? ive heard foam, self leveling concrete but never insulation. you mean the fiberglass stuff that gets put into walls?

and no, you do not need a board under the tank ( unless you want to do that to make your stand more sturdy) the edges will be just fine. i know this isnt what you mean but if anything does touch the bottom glass when the tank gets filled it will act as a "pressure point" and shatter out the bottom of the tank.

you may also want to inlcude a layer of eggcrate ( sold as "light diffuser" at hardware stores ) on the inside of the bottom of the tank. this does 2 main things. distribute the weight of live rock and act as a cushion incase your rock tumbles. simply cut the eggcrate to size, put it in, put your rock ontop and pour in your sand

thanks, fish! Yeah, I was talking about the thin sheet-type foam that they put around the exterior of homes nowadays.
Good point about the plywood underneath- I will dispense with that idea.
The eggcrate is a great idea. I was planning on placing the LR on bare glass before adding sand- your tip will work better. Many thanks!

I have used insulation for many years between the bottom of my tanks and the stand. I use the pink styrofoam type insulation sheets sold at Home Depot for about $8.00 for a 4' x 10' strip. The advantage is that your aquarium weight is naturally leveled. I'm not sure this would matter at all with a commercially prepared stand, but for home made projects, it can't hurt to be safe.

On the same principle as Pasfur, on my homemade stands, I use Cork Roadbed (for model railroading) The cork is firmer, and thinner, and works well for eliminating minor flaws.

If you are using a homemade stand that may have larger imperfections, the wood may be warped, or where the top may be torqued slightly, I would recommend the Foam board insulation as Pasfur suggested above.

Take pride in what you do, for it is a reflection of who you are.
