We have a pool that is 4 feet deep, 4 or 5 feet wide and 6 or 8 feet long. There are no pumps to it, and seeing how the house needs work Im not going to spend lots of money on the pumps for 3 weeks of having the pool. So I was thinking just making it into a greenhouse possible. The wife was thinking a koi pond. It is 1/4 or thicker fiberglass and in ground surrounded by patio. Who knows what Ill do inthe spring.
