Evolution Aqua K+ Media – Biological Filter Media

New for 2021

• Faster Filter Maturation
• Stable bio-film development
• Minerals added during extrusion
• Increased overall protected surface

New advanced filtration media

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

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

Class leading surface area

K+Mediais designed and manufactured in the UK by Evolution Aqua. This advanced media, with its innovative design, and class leading surface area provides enhanced biological and mechanical filtration.

As Evolution Aqua extrudeK+Media, 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 itslarge protected surface area, but also answers the problem of how tospeed upthe time taken tomature your filter.

Minerals added for faster filter maturation

During the extrusion process, Evolution Aqua add a range ofminerals, along withmagnesium,calcium,enzymesandsaltto the raw material that is used to manufactureK+Media. The result means thatK+Mediawillmature much fasterthan many other types of media.

– The addition of these minerals creates arough surfaceon the media. This textured surface has a microscopic honeycomb of peaks and craters that allow waste particles to collect, andnitrifying bacteriato form.

– The minerals act as afood sourcefor the bacteria, helping the bacteria todevelopandmultiplyat a faster rate, furtherimproving maturation times.

– Calcium alone hasproven advantagesfor developing and maintaining effective bio-films.

– Theenzymesthat 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 whichbio-film can easily adhere.

Increased surface area

With anew shapeandprofile,K+Mediahas also been designed to have anincreasedandclass leading surface area, meaning anoverall surface area of 1,350m2per m3. More importantly for biological filtration, theprotected surface area of K+Media is 1,025m2per m3. This allows astable bio-filmto form and remain intact when used in moving bed biological filtration, as in the newNexus+.

Stable bio-film development

The shape ofK+Mediaoptimises the amount ofquiet zoneswithin the media where a stable bio-film can develop. WhilstK+Mediakeeps the integral profile of K1 Media at its core, there is an extra layer of cells and fins around the outside of each piece that enable microscopic organisms such asRotifersandVorticellato thrive. This is an additional benefit as competitor media do not have suchquiet zonesthat would allow these higher lifeforms of filter feeders to develop. The bacteria and organisms that form within the bio-film ensure the media delivers optimum levels of biological filtration in the moving bed, which has beenproven filtration technologyfor many years in the fishkeeping hobby.

Use with PURE Pond products

Evolution Aqua also recommend usingK+Mediain combination with thePURE PondandPURE+ Filter Start Gelto boost bacteria levels which in turn will stick to the media andspeed up the maturation process even more.
