I have a Stenner pump installed on my pool for liquid chlorine. It is set up to run 6 minutes every two hours 5 times a day starting at 10am. It seems to work well at keeping my chlorine levels on target but I have had to adjust the run times on occasion. I wonder if I am losing chlorine to the sun by having it run during the day. Would it be better to run it for 30 minutes in the morning or evening when the sun is not directly overhead? Does it matter?
