Check chlorine level in pool water at least daily with a pool testing set and add this product as needed to maintain 0.6 to 1.0 ppm available chlorine. One pint of Clorox Bleach-Regular Scent per 6,000 gallons of water will supply approximately 1.0 ppm available chlorine.
Re: How long should a 3 chlorine puck last? an 8oz trichlor puck will have approx 5.5ppm FC for a pool of 10,000 gallons. So it will just depend on how much FC loss you have day to day. This day to day demand may vary a bit based on weather, bather load, leaves, pollen, algae, etc. If you are replacing every other day that's almost 3ppm a day and perhaps on the high side, but it's going to depend on your pool.
