hi
Would think it could be done but they're going to have a lot of equipment on them that would be useless as a fish pond .Also woukd be rediculously expensive for the size. I'm curious as to what would be the advantage ?? You want above ground heated ?? gary
sounds like a great idea! i would put it in the ground though and put rocks around it.... with enough rocks and plants you would hardly be able to tell it was a hot tub!
