Confused about CYA

[karrde97]

The trend I'm starting to notice is that on sunny days I need to add 2-3 quarts. Rainy/cloudy days 0-1quart.

Another question...Has somebody done a cost comparison of bleach versus chlorine? I'm curious since I'm putting so much bleach in per week.

Bleach IS chlorine, specifically sodium hypochlorite. Cost isn't the issue. Bleach, either as laundry bleach or the stuff you buy at the poolstore in higher concentration is the only thing that doesn't add something that will cause you trouble a few seasons down the road. Trichlor and dichlor add CYA. Cal-hypo adds calcium.
