This was my first summer using the BBB method and I'm a total convert! So much easier and cheaper than the pool store. My question is how much does the amount of bleach used change during the winter? I have been putting in half a 182 oz bottle each day and that's been keeping the water just about perfect, plus the occasional addition of muriatic acid. Also, do you test the water each day during the winter/off months? I don't plan to cover the pool until around February when the oak trees start dropping leaves.
