Evolution Aqua K1 Filter Media

Kaldnes Moving Bed process, which has been scientifically tried and tested in fish farming and waste water treatment for over 10 years, is now available for fish keepers and is exclusively distributed worldwide by Evolution Aqua. Thuis K1 media is engineered in a wheel shape and is slightly positively bouyant. This allows a small amount of water flow to circulate the media throughout the vessel. This flow is created with your air pump and air stones or diffuser etc.

Evolution Aqua K1 Micro Filter Media

K1 Micro Filter Media is specifically designed for use in bead filters, conventional pond filters and aquarium filters. K1 Micro media has the same wheel shaped design as K1 Media, but it has an increased protected surface area of 950 m2 per m3.
The wheel shaped structure of K1 Micro is designed specifically to create the most effective environment for the nitrification process to take place. As K1 Micro media matures, bacteria colonises in the “quiet areas” of each piece of media helping to improve nitrification / de-nitrification. This enables a well-balanced biological equilibrium to be sustained in your pond to keep fish healthy and the water crystal clear.

Evolution Aqua K Plus Advanced Filter Media

Evolution Aqua K Plus Advanced filter media is a plastic media, for use in biological pond filters, specifically in moving bed bio reactors, and was pioneered by Evolution Aqua, some 20 years ago. In recent years, other plastic media have come onto the market, usually with the aim of trying to get more and more surface area. However, one drawback to using plastic media has always been the time it takes to establish a stable biofilm essential for good filtration.

Evolution Aqua K Plus Advanced Sinking Filter Media
