the water was very cloudy to start but I've been shocking the pool and now its clear but not crystal clear. I was using pool shock rather than chlorine since its a little more convenient and I had some leftover from last year.

the bleach calculator says I need about 7 gallons of bleach to reach 15ppm. I typically shock the pool once a week after heavy use or heavy rainfall, so thats a lot of bleach to keep on hand. I guess I've seen a split of opinion in these forums on whether one needs to shock regularly if the chlorine readings stay in acceptable range.
