Biofilter perfect for large freshwater or saltwater aquarium tanks, fish koi ponds, hydroponics, aquaculture, and aquaponics.

Key Features:

• Floating moving bed filling: This biofilter media is meant to be moving at all times by air or water current. It can be used indoors or outdoors. When used for aquarium sump tanks, you may need an air pump to put some air into the water to make the filter media move. It would be more efficient if there were microbubbles in the water.
• Easy to use & Less maintenance: It’s very easy to use the biofilter media, just pour the media into the water of the sump tank. You wouldn’t have to clean it at all, just let the media stay where they are, then change the water regularly.
• Get more surface area: A small cylinder’s inner space is divided into 5 equal parts. The inner and outer walls of the cylinder are filled with extrusive stripes which largely increase the surface area with water. It’s good for biofilm formation and the growth of beneficial bacteria. The K1 filter media is the most efficient in moving the media biofilter system for aquariums.
• Wide filtration application: This filter media can be used for freshwater and marine aquariums, koi ponds, aquaponics, aquaculture, and hydroponics filtration. You can use this in places where water filtration is needed. The biofilm formation time is 15 – 30 days.
