I have a 16' intex ultra pool which I kept up all winter. Today I took the cover off the pool and the water was perfectly clear and beautiful but I noticed something rather odd. There were about a dozen earthworms drowned at the bottom of the pool. There is no sign of a leak, so I am quite sure that they did not climb in through the bottom. They were not in one spot, but spread out all over. How did they get there? I can't imagine they climbed 4' up the side of the pool.
It doesn't really matter in the end, but I am curious to know how this could have happened.
