New pool, been working to balance everything out, so clean and beautiful. I read the forum every day and everyone is having so much fun taking care of their pool, and here this morning I was a bit jealous that I have nothing to do because my pool is so pretty. Then my wife gets in for a swim and says, “hey, there is a swimming bug in here!” Sure enough, I pulled this thing out which I assume is a backswimmer?

I’m kind of surprised because my FC has been in the target range. I need to had a little more CYA to get to 70 and planned to raise FC just a little more, but dang I was shocked to find this swimming bug having a great time in my pool without my permission. I removed it, squished it, tested (the one day I hadn’t tested yet) and FC is at 5.2. I added just shy of a quart of 10% and the SWG is going which I’m guessing will get me to around FC 7 today with the sun in full effect.
My question: what should I target my FC at to keep these guys from having a party in my pool. Where there is 1, there will be more! How did they find me in the first place? What gives?
