Treating a pool algae outbreak involves testing your water, brushing your pool walls and floor, shocking your pool, using algaecide, filtering your pool, cleaning your filter, and monitoring your water. By following these steps and being vigilant about maintaining your pool, you can prevent future algae outbreaks and enjoy a clear and healthy pool all season long.

Regular backwashing and cleaning of your DE pool filter is essential to ensure that your pool stays clean, clear, and healthy for swimming.

In general, pool owners should aim to clean their cartridge pool filter at least twice a year. If you use your pool frequently, have high bather loads, or if you have a lot of trees in close proximity to your pool, you may need to clean the filter more often.
