Picture this: It is the first warm, sunny day of the summer season and you decide to take a dip in your backyard pool. You don your favorite bathing suit (a little snugger than last year!) and grab a towel. As you open the gate to your swimming pool, you stop dead in your tracks. The pool is littered with leaves, debris and what is that green stuff floating in the corner? You toss down your towel and grab your skimmer. So much for swimming!
