Introduction
The circulation pump and filter are the “heart” of any pool system. Without adequate flow rate and efficient filtration, water quality and sanitation can quickly deteriorate.

Essential Tips

• Choosing the right pump size: Calculate by dividing the pool volume by the desired turnover time (e.g., 6 hours for large pools).
• Higher flow for small pools: In a children’s pool, turnover might be 2 hours, meaning a relatively higher flow rate is required.
• Backwash schedule: When flow rate drops by ~20% from normal, or if the filter pressure gauge shows a significant increase, perform a backwash to clear the filter media.
