What if I don’t know my pump flow rate?

Check the pump label/manual for rated flow. You can also estimate from filter pressure and manufacturer flow charts.

Will longer run-time always improve clarity?

Circulation helps, but water chemistry and filtration are equally important. Balance chlorine, pH, and filter maintenance.

Pool Pump Turnover & Daily Run-Time Calculator (Free)

Q: How many turnovers per day should I run?

Many pools target 1–2× per day, but follow your pump and filter manufacturer guidance and local regulations.

Work out how long to run your pump each day. Enter your pool volume and pump flow rate to see hours for a full turnover and recommended daily run-time (1.0×–2.0×). Supports metric and imperial units.

How to use the calculator

Enter pool volume (L or gal). Tip: use our Pool Volume Calculator first if you’re unsure.
Enter pump flow (L/h, L/min, gph or gpm).
Select turnovers/day (many pools target 1–2× per day).
Click Calculate to see hours for 1× and your daily run-time.

Example: 60,000 L pool, 12,000 L/h pump → one turnover ≈ 5h. At 1.5×/day → ≈ 7h 30m.

FAQs

How many turnovers per day should I run?

Common guidance is 1–2× per day, but follow your manufacturer’s advice and local regulations.

What if my pump flow rate isn’t listed?

Check the pump label/manual or your filter pressure gauge + flow chart. You can also estimate from manufacturer specs.

Does longer run-time always mean cleaner water?

Up to a point, yes—but water balance, filtration, brushing and skimming matter too. Aim for consistent circulation.
