Kaldnes K1

How it works

Maturing the K1 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 colonise, more than other types of static media. It is this process which removes harmful ammonia and nitrite from the water.

What is meant by ‘self cleaning?

Unlike foam, matting, or other forms of static filtration media, the K1/K3 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 grammes of food per day and for K3, 225 grammes of food per day. For retrofit of existing filters, K3 Media is the most suitable due to its larger size and ease of control.
