Rinse media before use. Media can be placed directly into the aquarium, reef sump, canister filter, wet/dry filter, or hang-on-back filter. The included bag helps keep media contained within the filter. For best results, seed the media with your choice of bacteria culture like Fauna Marin Bacto Blend by soaking overnight before adding it to the aquarium.
For optimal results, rinse the media with tank water and gently scrub the surface debris every 12 months. Replace media every 5 years or as needed. Add additional media to increase the biological capacity of a filter system.
