How long should a pool run each day?

The ideal running time for a swimming pool pump depends on several factors, including pool size, water temperature, climate, and bather load. Here's a general guideline to help you determine how long your pool pump should run each day:

1. Pool Size:

- Small pools (less than 15,000 gallons): 8 to 10 hours per day

- Medium-sized pools (15,000 to 25,000 gallons): 10 to 12 hours per day

- Large pools (over 25,000 gallons): 12 to 14 hours per day

2. Water Temperature:

- Warmer water (above 80°F): Increase running time by 1-2 hours per day.

- Cooler water (below 80°F): Decrease running time by 1-2 hours per day.

3. Climate:

- Hot and dry climate: Increase running time by 1-2 hours per day.

- Humid climate: Decrease running time by 1-2 hours per day.

4. Bather Load:

- High bather load (5 or more swimmers per day): Increase running time by 1-2 hours per day.

- Low bather load (1-2 swimmers per day): Decrease running time by 1-2 hours per day.

5. Additional Factors:

- Pool covers: Using a pool cover when the pool is not in use can reduce evaporation and the need for pump runtime.

- Saltwater pools: Saltwater pools generally require less chlorine and may run for slightly shorter periods.

- Variable-speed pumps: If you have a variable-speed pump, adjust the speed and runtime based on the conditions mentioned above.

Note: These are general guidelines, and actual pump runtime may vary. Adjust the running time as necessary to maintain proper water clarity and chemical balance in your pool. Consulting with a pool professional can also provide personalized recommendations based on your specific pool and conditions.
