I need help. We have a 15'x48" Intex metal frame pool. Last year was great, we were newbies, made some mistakes (not totally level), but all in all a great experience. Took the time to level out area, put in border stones, laid a bed of sand, got the pool out and up, and lo and behold, we apparently have a leak. Only got a couple of inches of water in the pool before we noticed a tiny bit of water pooling around the base of a leg, let it go until there was about a foot of water in pool, and now have water pooling around another leg (the two legs are next to each other), only about 2 cups of water at the most. Have been reading and contemplating...no water on pool walls, so I'm guessing it's on a seam or in the bottom. Advice? How hard is it to find a leak on the bottom? What about these "fix-a-leak" products?
