Not sure of the volume? Use the volume calculator. A 0.75–1.0 kW pump suits most home pools.

Indicative sizing — real flow depends on pipe size, head and filter. A variable-speed pump run longer at low speed is usually cheaper and quieter than a single-speed pump. Aim for at least one full turnover a day.
