For an average adult swimmer, a minimum counter-current flow of 1500
litres/minute is required for adequate performance while an optimal system
should deliver in excess of 1800 litres/minute back into the pool or spa. A
high performance optimal system should deliver at least 2200 litres/minute.
Please note however, no swim jet system can be completely resistive to a
high performance swimmer. Typical counter-swim systems include single or
dual high-capacity pumps, controls, and in-pool delivery system.
