I filter every day for an hour. Sometimes twice a day. I have a monstrous jacuzzi pump. This helps keep the water clean and the water temp even. In the past I used bromine, but now I use a couple of tablespoons of hydrogen peroxide once a week. I haven't read any studies that specify exactly how long you should keep the same solution, but commercial places usually change it once a year. One place said you could use it up to 3 years.
