I live in Eastern PA and every year when I open my pool it requires 60+ jugs of bleach. I opened the pool today which is early and as usual the pool looks good I can see both drains and the deep end, the pool is just cloudy. I tested the water and found zero CYA so I brought it up to shock level 3 times and it drops to zero within 2 hours. I have been running around today and can't babysit the pool. Anyhow, because the pool requires, so much effort in the beginning of the season with the BBB method I'm thinking next year I will just hit it with Cal-Hypo and then switch over to Bleach after the first week. The pool guys can't sit around and babysit a pool, so what do they do? Any thoughts on this especially those of you that have to close your pool in the winter months. By the way, I have been using the BBB method for over 4 years and really like it, it's just the opening that makes me go nuts. Thanks
