We're buying our first home and it has a pool. The pool hasn't been used in at least 6 months and the pool cover is floating in the water. The water is black and all you can see is the occasional toad on the surface. It's bound to have leaves and sticks and dead bodies at the bottom. My family says to drain the whole thing and start over, but others tell me this is dangerous. The pool is in ground with a vinyl liner. Any advice or alternatives is appreciated.
