Hagen Fluval Pre-Filter Media (750 Grams)

Pre-Filter media is the front line of attack for particles in your aquarium. For use in salt and fresh water environments, this media works with your fluval filter to catch larger particles and prevents clogging and wasting your more expensive filter media.

Before using this product we recommend that you rinse it and place it in the bottom filter module of your fluval filter. The product can be easily reused by rinsing it with the aquarium water left over from a water change.
