Product Features

Floating moving bed filling

This bio filter 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 water to make the filter media move. It would be more efficient if there are micro bubbles in the water.

Easy to use & Less maintenance

It’s very easy to use the filter 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 at where they are, then change water regularly.

Get more surface area

A small cylinder inner space is divided into 5 equal parts. The inner and outer walls of the cylinder is filled with extrusive stripes which largely increases surface area with water. It’s good for biofilm formation and the growth of beneficial bacteria. The K1 filter media is most efficient in moving media bio filter system for aquarium.

Wide filtration application

This filter media can be used for fresh water 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.

Directions for Use
