How to Use This Calculator
- Enter your pool's volume in gallons. You can find this information in your pool's manual or by multiplying length × width × average depth (for rectangular pools) and multiplying by 7.48 (the number of gallons in a cubic foot).
- Enter how many hours per day your pool's filter system runs. This information is usually found on your filter pump or in your pool equipment manual.
- Click the "Calculate" button to see your pool's daily turnover rate.
Understanding Pool Turnover Rate
Pool turnover rate is the amount of water that passes through your pool's filtration system in a 24-hour period. It's expressed in gallons per day. A proper turnover rate helps ensure that all water in your pool is filtered through the system at least once per day.
Typical Turnover Rates
- Shallow End Pools: 4-6 hours of filtration per day (resulting in a turnover rate of 4,000-6,000 gallons per day)
- Deep End Pools: 6-8 hours of filtration per day (resulting in a turnover rate of 6,000-8,000 gallons per day)
- Overhead Spa Pools: 8-12 hours of filtration per day (resulting in a turnover rate of 8,000-12,000 gallons per day)
Why Turnover Rate Matters
Proper turnover rate is essential for several reasons:
- Ensures all water is filtered regularly, helping maintain water clarity and sanitation
- Prevents stagnant water in certain areas of the pool
- Helps maintain proper chemical balance throughout the pool
- Reduces the risk of algae growth
