K1 & K1 Micro Media is the ultimate in Biological filtration!
This media is specifically designed to be used as part of the fluidized bed filter - moving all of the time. Moving the water through it all of the time maximizes it's filtration capabilities. Originally designed to be used in the Nexus 220 and Nexus 320 filter units, this media can also be used in may other applications.
Maturing the K1 Media bio-media is important because a delicate eco-system is naturally developing for the bacteria involved in the nitrification process. K1 Media provides the maximum active surface area for the bacteria to colonize, more than other types of static media. It is this process which removes harmful ammonia and nitrite from the water.
As the K1 Media moves within the filter, it causes the old dead bacteria on the outside to be displaced. This makes space for new younger heavier feeding bacteria to rapidly colonise. Within the wheel is a protected surface which enables colonies of bacteria to naturally follow their lifecycle, of maturing, dying and then fueling the latter stages of the nitrification cycle. K1 Media has been designed to provide the best possible habitat for both young and mature beneficial bacterial colonies.
Unlike foam, matting, or other forms of static filtration media, the K1 Media is designed to move freely within your filter. The constant chaotic movement of the air from your pump, causes the media to self-clean and thus requires no maintenance. This allows the filter to reach optimum effectiveness without the disturbance of periodic cleaning, avoiding unnecessary loss of bacteria within the filter. 50 Litres of K1 media will handle up to 250 grams of food per day and for K3, 225 grams of food per day. For retrofit of existing filters, K3 media is the most suitable due to its larger size and ease of control.
The more food you give to them, the darker it gets as it coats with a biofilm.

Great product!!! Thank you Play It Koi
So far I have ordered a Sieve, Nexus 220 and K1 media and all have arrived quickly, would recommend this vendor!
This K1 media is the best for fluidized bed filters. Really excellent stuff!
Overall greatness all around. thanks! will be back
