K1 Micro is an even smaller version of standard K1, measuring approximately 6 x 6mm. The polyethylene media has a specific wheel-like shape, with a cross-shaped central portion. By shrinking the size of the media, EA has managed to up the surface area per unit volume, allowing for more space for bacterial colonisation. However, surface area isn’t everything — it’s what you do with it that counts — and K1 Micro has a neat feature that allows more than just bacteria to colonise it. How does it work? There are two main ways to use it, and combining the two can make for efficient mechanical and biological filtration. As a static media, K1 Micro does work biologically, but its primary use in this respect is to trap solids. The media’s structure collects suspended particles, and it can then be backwashed (most effectively with air) to clean this away. This is the basis of the Nexus Koi filter’s mechanical filtration, and with a little ingenuity, this could certainly be applied to an aquarium filter. As a moving bed biofilm reactor (MBBR), the medium’s inner surface is where the magic happens. A biofilm builds up (and bear in mind this can take some time), but it’s constantly agitated courtesy of aeration, pumped flow or even just through sitting passively in a turbulent region of a sump or filter chamber. This sloughs off excessive biofilm, making the media effectively self-cleaning if utilised in this way. Nevertheless, the protected inner sites resist sloughing to a sufficient extent to allow various communities to survive unharmed. It’s a simple yet elegant idea.
