I have an old 7 ft x 7 ft fiberglass spa shell that I am thinking about turning into a Koi pond. Is this doable or would I be
better off starting a pond from scratch. 3 sides have built in bench seating and one corner has steps all of which could serve as support for potted water plants. The 4th side was a curved lounge that I thought a few well placed rocks could form a hideout for the fish. There are 4 plumbed jets and a drain / return close to the bottom. I would NOT use the old spa equipment but would plumb a bio filter and pond pump to circulate the water.

I'm not sure of the number of gallons. If not large enough for an average Koi pond I thought I could just build up another level from the spa lip. That leads us back to the original question if it would just be better to start from scratch.

Thanks,
