So, this is our first season with our pool, a 24' above ground. We just bought the house in December. Anyway, I uncapped the pool earlier in the week and have been slowly clearing the thing up, it was quite a mess. I've noticed something odd .. the birds seem to be making regular bathroom runs directly AT and in our pool. The deck is taking quite a beating, it looks like someone splattered paint all over it at this point. This was NOT happening prior to opening the pool. Is this normal? And if so, does anyone have a suggestion for stopping it?
