So when closing I pulled the ladder out, it is a Confer or something like that plastic ladder that you put water in the legs to stop it from floating. When I pulled the ladder the water that was in the pool dumped (outside the pool) and was green as anyhing even though pool was clear. So I was thinking next summer using my drill pump to pull the water out of the ladder legs every week or so and refilling. Or maybe add some bleach mix to the ladder leg and fill. Any one else ever experience this? Suggestions?
