You should clean your swimming pool filtration system every 4 to 6 weeks for optimal performance. However, the frequency may vary based on pool usage, debris, and environmental conditions. If your pool is used heavily or surrounded by trees, you may need to clean it more often. Check for signs like reduced water flow or cloudy water, which indicate a dirty filter. For cartridge filters, rinse with a hose or soak in a cleaning solution. Sand and DE filters may require backwashing. Regular maintenance extends the lifespan of your filtration system and keeps your pool water crystal clear. Trust DS Water Technology for expert pool care solutions.
