Thanks for the help.
It will depend greatly on your bather load, sun/shade situation and whether you add stabilizer. A cup of bleach will raise your chlorine level by about 1ppm in that pool. Your use will vary from day to day with weather and use. You can add cyanuric acid, also known as CYA or stabilizer to the water which will slow down your chlorine consumption. Read the posts at the top of the Using Chlorine... forum for some good info. You may also need to adjust pH, but what you need to add will depend on your water.
