We bought a house with our first pool ever in April. It turned green in late May, and we converted to BBB in early June. I noticed a slight uptick in bleach use during late July/August as we hit peak temperatures. Now that the temps have dropped off, I'm able to use a little less - 4-5 cups a day versus 6+ to hold about 1.5 ppm.

It really makes no sense to close this pool since we can have 90 degree days in January, but I was wondering if the average temperature will affect chlorine use as we head into winter.
