ya very true dont know if ya could cut windows in it and use acrylic or not

 

Seascapes has already done this with their shark pool.

 

A guy that owns a pet store here in my town said he used to have one made out of plywood and pond liner, with a glass window in the side. I think he said it was 600 gallons or so, and he had a couple sharks in it. With something like that I think you would get major moisture and mold problems though.

 

There is a guy that stopped in the store the other day that said they had two 500 gallon salt ponds in their basement

 

There used to be a LFS here in town that had a SW tank in a hot tub. It was pretty neat.
