Fluval 4 Foam Sleeve Insert

Contains 2 Foam Sleeve Inserts

This Fluval 4 foam sleeve insert is specifically designed for the Fluval 4 internal filter. It functions as an effective mechanical media to remove debris from the aquarium. Foam also encourages populations of beneficial bacteria which are important for proper biological balance in the aquarium.

(NOTE: Nitrifying bacteria require time to become established. Lack of nitrifying bacteria in a new set-up may result in the aquarium becoming cloudy. This normally clears as the nitrifying bacteria begin to become established.)
