For the past two days I've seen a handful of water boatman alive in the pool and a few in the skimmer. Based on my reading they are a sign of algae. I don't believe that's the case in my pool because they showed up right after a hard rain for most of the weekend but I had my chlorine level elevated since we were out of town for the weekend. It was 11 when I left town Fri morning and 9 when I got home Sunday. Cya 45. Water is clear and I've been religiously keeping chlorine level on the high side of normal, literally never dipped. All other levels are perfect since I'm somewhat obsessive about them. So my question is, why are they around and how do I evict them?
