Yes, both K1 and K1 Micro are suitable for mechanical filtration, due to its compact size K1 Micro is usually preferred

Yes, both K1 and K1 Micro are suitable for biological filtration, K1 is usually preferred in biological filters like you would find on a pond. K1 Micro is ideal for static or moving bed filters on aquariums

Moving bed media has many advangates over traditional static bed filters including a huge surface area which is always exposed to maximum oxygen and food for the bacteria, self cleaning media as it tumbles, and the world famous protected surface area, enabling bacteria and higher organisms to dwell in their preferred location inside the media, exposed to oxygen and food, but safe from harmful cleaning practices.

In a moving bed chamber - You would want no more than 25% of the chamber to be filled with K1 as this allows enough water to help it to be fluidised properly.
