For koi enthusiasts and professionals, only the highest-quality equipment will do. OASE's advanced filtration systems, energy-efficient pumps, and precision-engineered aeration technology provide the perfect balance of performance, reliability, and water clarity - ensuring koi thrive in an environment as pure as nature intended.

Pump-fed system or gravity-fed system?

Will the filter be located above or at the height of the water level? The answer to this is important, because the maximum flow rates of a filter also depend on its installation type and location. Filters that are operated with a pump are often above the water level. Filters that use gravity are placed at the height of the water level.

Pump-Fed-System

A pump-fed system, on the other hand, enables a pump to actively pull water from the pond and push it through the filtration system, providing more control over water flow but requiring external power.

Gravity-Fed System

A gravity-fed pump in koi ponds uses the natural flow of water, relying on gravity to move the water through the filtration system, ensuring efficient filtration and minimal energy use.
