I'm am having trouble getting enough chlorine in my pool this year. I'm in Michigan and it has been an unusually hot summer. (That's a good thing by the way!) All of my water chemistry is in balance except my chlorine. I can't get enough in the water to hardly register on either a dip stick or a liquid test kit. I have an automatic chlorinator that holds 12, 3" tablets. The pump is running fine and the chlorine is moving into the pool at about the expected rate. The water is crystal clear and I'm having no alge problems. PH looks good, stabilizer is in range and alkalinity is right where it should be. But no chlorine. The water has hovered right around 90 degrees most of the summer. I'm assuming it is just burning the chlorine out almost as fast as I get it in. I do throw a couple extra tablets in the skimmer once in a while just to try to push the levels.
Should I just leave well enough alone or is this something I need to be concerned with? I had a chlorine lock issue a few years ago and it was a pain in the butt to deal with not to mention extremely expensive. I hate to have to go through that process again if it's not necessary.
