I am going to go off script here just a bit. I am sure someone will set me straight if I am out of bounds. I do not check my chlorine every day. There I said it. I did for a while and established what my pool consumes on a daily basis. I then take that number (lets say 2.5ppm per day) and just add that much per day. I do a full work up of tests on Saturdays. I will run an occasional powder chlorine test during the week once just to see how things look. If the weather is very cloudy or rain then I take a .5 ppm off. When it gets hot it moves up to a full 3 ppm per day. So far so good and the water is beautiful. My neighbor came over the other day to borrow some pucks - he knew I had a pool and he wouldn't be able to get to the pool store for a couple of days. The look on his face when I told him how I cared for my pool was priceless. Then he walked out back and looked at the water. "I have never seen my pool with water that clear" - was his statement. I think we have a convert.
