K1 media has been used by Evolution Aqua in Koi filtration systems for a number of years. K1 Micro contains all of the benefits of traditional K1 media but is extruded in a much smaller form. The small wheel shaped filter media pieces provide a significantly increased protected surface area per cubic metre when compared to standard K1 for bacteria to colonise. This makes K1 Micro an ideal filter media for aquariums of all types where high level biological filtration is needed. K1 Micro can also be used to replace existing filter media. 


How it works.

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

Kaldnes micro 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.

How it is different to other media?

As the Kaldnes micro 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. 

Kaldnes 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 Kaldnes K1 micro 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.
