You can't just use a blanket statement, like 1 gal of bleach per day per 10,000 gallons. I gal of 6% bleach will raise chorine 6ppms in a 10,000 gallon pool. What you use will all depend on your bather load, cya and sunlight on pool. You can go back and read all of the stickys - and some old posts, they are a wealth of information. Untill you post your true numbers, we can't give you specific details.
