Yet flow rate directly affects nearly every aspect of your aquarium's health. Nutrient Distribution In a planted aquarium , water flow carries dissolved CO2 and fertilisers to every plant in the tank. Without adequate circulation , plants near the filter outlet thrive while those in low- flow corners struggle.
Calculate the ideal aquarium flow rate for your tank to ensure optimal circulation , filtration, and fish health. Use our free aquarium flow rate calculator for fresh and saltwater setups.

Aquarium circulation pump sizing depends on two factors: tank volume and the type of aquarium . The flow rate target represents total water movement from all sources combined — filter output plus any additional circulation pumps or wavemakers.
