Here's a thought!

There must be something in my coffee.

Been sitting here, pondering a new tank. I like the number 75 so, 75 gallons is what I want.

A custom made tank made mostly of marble. Bottom, back are solid marble. Sides and front like window frames.

Marble would look like this:

I am thinking this tank would be crazy heavy. But meh... :D I'd use white sand to give it a dramatic effect, maybe even go with real plants.

Whacha think?

Depends. What fish do you plan to keep.

Marble raises pH. It is basically limestone. If you don't plan t keep rift lake cichlids or similar you will need to seal it (the marble) very well.

Sounds cool, but it would probably be easier to use some linoleum counter top or something as a background, and build a window frame/box around the whole tank. That way you wouldn't have any weight issues!

If you build a tank out of marble you will not be able to move it without a fork lift.You will have trouble in later years with the sealent peeling off the marble.You would have a world of headaches with that,but it would look cool.
I agree with Lindsey on this.Get a glass tank and get some marble like laminent and use it as a background.

that wouldnt work too well. you could however put marble under the tank and on the outside of the back
