I cannot help you with doses of the Bioguard products because I don't use them. My pool only gets fed with bleach, baking soda, borax and occasionally CYA. (Don't be afraid to use bleach. It is 6% sodium hypochlorite, pool store chlorine is the same thing but only a higher % at 12.5% (usually).

For reference, in your pool, each quart of 6% bleach will add approximately 1ppm of chlorine. Use that to help you figure out needed doses.

When your kit arrives, run a full set of numbers and post them.
