i'm a committed BBB method user, but like to have some pucks on hand for when i'm away, and when i need to refurbish CYA levels. i'm also kind of a nut about getting the best deal, so i like to figure out the actual PPM of chlorine i'm adding per dollar for each chlorine source. (for those in the midwest, it turns out the best deal i've found is the tundra bland bleach at the Aldi chain of bargain grocery stores - $0.99 per 96 ozs., yielding 2.27 PPM chlorine per dollar in my 20k gallon pool.)
anyhow, when you look at the label on trichlor packaging, it tells you what percent is trichlor, and what percent is inert. what it doesn't tell you is what percent of the trichlor is actually chlorine, and what percent is CYA and whatever other stuff makes up trichlor. anyone know?
