>????? chemicals

[bof]

Hi
Now that the water temp by mid afternoon is at 18 - 20 celsius but it is still warm enough to potter about in polo shirt and shorts. I am suprised that I have not had to use any chemicals for the last two weeks. The water looks good and tests are in range but the chlorine has not decreased. Is this normal for this time of year.

There will be a dramatic drop in FC demand usually. Temps affect it a great deal, and cooler one generally slow down chemical reactions a great deal.
