Customer-Facing Q&A
Q: How often do I need to clean the cartridges?
A: Cleaning frequency depends on pool use, debris load, and pump flow, but the large-capacity design significantly extends time between cleanings compared to smaller filters.
Q: Does this filter require backwashing?
A: No. This cartridge system does not require backwashing. Simply remove, rinse, and reinstall the cartridges for fast, effective maintenance.
Q: Is it suitable for saltwater pools?
A: Yes. The corrosion-resistant materials and solid construction are fully compatible with salt chlorination systems.
Q: Which pump should I pair it with?
A: It pairs best with variable-speed or two-speed pumps sized appropriately for your pool volume and plumbing layout, ensuring balanced flow and efficient filtration.
Q: What are the benefits over a smaller filter or sand/DE system?
A: The Clean & Clear Plus 520 provides greater cartridge surface area (thereby higher flow and clarity), quicker maintenance (no backwashing), and reduced water waste—ideal for high-demand environments.
