Need help deciding on Glass or Acrylic for large tank

The tank I am plainging will be 11ft long 3 feet wide and 2ft tall. I am trying to make up my mind on Glass or Acrylic. What are the pro's and cons of both.
 
The glass you will need will be very very heavy, I have been told Acrylic gets cloud over the years, but I have no experience with it, since I have glass, again that is what I was told at my LFS.

do a search there are positive and neg to both
Agreed indeed!
I personally do not like acrylic, it scratches way to easy and over time tends to get small hairline cracks that are visible when looking at the tank from the side.

Good lord Brad where you putting this beast? You could probably save quite a bit of money going with 10' instead of 11' i would imagine.I would hate to have to lift a glasstank that heavy up on the stand.I helped a guy who has a 450 gallon (10x3x2?)and it was a 10 guy operation.
 
I know my 240 was hell on us trying to get it in the house and on the stand. That was with me and 3 other guys and I was the smallest of the 4
 
If you are considering acrylic, I'd advise shortening the tank to 10'. 10' is the longest standard sheet made in this country. Going longer involves either A) "casting" 2 sheets together (end to end) which gets much more expensive or B) ordering 6 x 15' sheets from RPG Asia which will also get much more expensive.
With glass, cannot say - I simply dunno :)

HTH,

If your going that big I think you almost have to go acrylic just for the weight of the tank and being able to move it.
 
I'm at least two years away from starting a project for my giant tank (even if I ever do it), but I've been wondering the same thing.

What would be the expected longevity of a tank that size made out of glass or acrylic? What would be the safest bet in terms of leaks and/or seam failure?

How long does it take for acrylic to start to fog up? Is there anything you can do about acrylic fogging up (like drain the tank and re-polish it?)

With a glass tank, couldn't you just cut a piece of acrylic to place in front of the viewing area of the tank to help provide shatter protection?

Sorry if I'm hijacking the thread here....
 
Perhaps the easiest was to describe the two is glass is glued together usually with a silicon based adhesive. Acrylic is welded together chemically. The joint on a properly assembled acrylic tank will rarely ever break. We've all heard of joints bursting on glass tanks - or the glass itself. The offset is acrylic is soft and scatches easily. Special scrapers and care must be used as those for glass will destroy an acrylic tank. Kids and acrylic don't mix.
