240G build-styrofoam?

[jh2pizza]

Getting ready to begin building our new system. I have a new Glass cages tank. They call for styrofoam under it. But no specs.

How thick, the entire bottom or just the perimeter?

Every manufacturer is a little different. I wouldn't risk it and just call glass cages and ask what they want. If you use the wrong foam they could void any and all warranties.

Call and make sure so you don't loose your warranty

I have a glass cages 240g long... sitting on a DIY stand I built .. I doubled the plywood layer but once it got here decided not to use any foam.. reason was the same as yours there were no specs for what type and dimension of foam to use... called them and they said its an optional recommendation.. mine is been running about 5 yrs now, no issues whatsoever .. they also said that it wouldnt void the warranty if I didnt use any

The foam is meant to be used in case the stand surface isn't 100% flat, iirc. That way the load is spread evenly.

I used the foil backed foam from Home Depot on my 240g glass cages built tank. It's about 1" thick.

There's a type of foam board that is high density used underneath poured concrete floors in basements. It is approx 1" thick. Available at most bigbox hardware stores as others have mentioned above. Foil not necessary.

Not sure the 1" thick is necessary, is it?
Back when I used it, 1/2" was recommended.

Whatever is available in your locality. You shouldn't have any bumps or dips greater than 1/8" for the foam to compensate for anyway.

does the tank have a frame at the bottom? or does it sit on the glass?

glass. I picked up 1/2" foil covered R=Tuff

Mind if I ask how you like the tank and if it was shipped?

I am looking at the 235 tall. It has a good width and depth. Height is interesting so will plan foe a certain reef bio type. Their tanks seem pretty reasonable.
