How it works

Maturing the k1 filter media bio-media is important because a delicate eco-system is naturally developing for the bacteria involved in the nitrification process.

k1 filter 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.

How it is different to other media
As the k1 filter 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 colonize.

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.


What is meant by ‘self-cleaning’?

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 Liters 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.
