Evolution Aqua K1+ Filter Media + Minerals & Enzymes- 2.5L

 USUALLY IN STOCK - ALTERNATIVELY 3-4 WORKDAY LEADTIME 

K1+Media is designed and manufactured in UK. This advanced media, with its innovative design, and class leading surface area provides enhanced biological and mechanical filtration. Minerals and Enzymes are added to the raw material. The result of this process, unique to Evolution Aqua, is a filtration media that not only outperforms most of its competitors due to its large protected surface area, but also answers the problem of how to speed up the time taken to mature your filter.

Plastic media, for use in biological pond filters - specifically in moving bed bio reactors, 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.

After many years of research, Evolution Aqua have now developed a new media that not only gives class leading surface area, but also overcomes the problem of long maturation times.

During the extrusion process, Evolution Aqua adds a range of minerals, along with magnesium, calcium, enzymes and salt to the raw material that is used to manufacture K+ Media. The result means that K+ Media will mature much faster than many other types of media.

• The addition of these minerals creates a rough surface on the media. This textured surface has a microscopic honeycomb of peaks and craters that allow waste particles to collect, and nitrifying bacteria to form.
• The minerals act as a food source for the bacteria, helping the bacteria to develop and multiply at a faster rate, further improving maturation times.
• Calcium alone has proven advantages for developing and maintaining effective bio-films.
• The enzymes that are added also help to make the media “sticky” so waste particles can adhere to media easier.
• Salt is added during the extrusion process, which is dissolved during the cooling process, leaving a rough surface on which bio-film can easily adhere.
