This will probably not come as a surprise, but if you see a crack in your fiberglass pool, you should repair the swimming pool immediately. If water gets into the surface layer, it can cause the fiberglass substrate to rot. You can buy fiberglass patch kits at swimming pool and spa dealerships, auto body supply houses and watercraft dealerships. One more thing: *Always leave water in a fiberglass pool until you are certain that there is no water under the pool. If you remove all the water from a fiberglass pool that has too much water under it the pool could float out of the hole, which could do serious damage to the pool and the plumbing.
