I'm looking at doing something similar. the problem I'm having is finding a stock tank 600 gallons or so with no ridges on the inside.keep us updated with what you come up with.I'm thinking the sides need to be smooth to seal the glass to it.can you add your own window to a indoor pond. Like cut out the hole and use plexy. Just seal it to the inside.
well what im thinking is a 8ft long x 2 ft high side made with wood with a liner in it but one side will have a window in it maybe 7ft x 1 1/2 ft. can I make it work
