I have an inground pool in south Florida, 15' x 30', 12,000 gal. There is an area on the bottom, about 1 foot in diameter where some coating is peeling up. If I pick off a piece, it appears to be a fiberglass layer, under which I see what looks like concrete. The remainder of the pool is in very good condition.
Is there a way to repair this small piece of missing coating on the bottom? I'm afraid to drain the pool, fearing the pool will float. We are near the ocean, and the water table seems to be about 2 feet down.
Recommendations, from do-it-yourself to hiring a repair contractor would be appreciated.
