        			Official K1 Moving bed filter media from Evolution Aqua 50L bag delivered in an unopened Evolution Aqua bag. All other sizes are measured out manually from a official Evolution Aqua 50L bag and sent in grip seal bags. 50 Litres of K1 media will handle up to 250 grams of food per day K1 total surface area: 800M2 K1 Total protected surface: 500M2 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 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 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 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.
