Choosing the Proper Flow Rate for Your Aquarium

Choosing the Proper Flow Rate for Your Aquarium

This is essential for filter feeders. The following types of tanks do better with slower flow rates Live plant tanks. Decreasing surface agitation helps hold in the CO2 much needed by plants. Most plants cannot tolerate being in the middle of the flow stream. Small fish, baby fish, and betta tanks need a very slow flow rate.
