Evolution Aqua K3 Plus Advanced Filter Media 50 Litres

The Evolution Aqua K3 Plus Advanced Filter Media provides a floating filter media ideal for use in both moving and static bed filters. K3+ Advanced Filter Media has improved versatility due to its larger size making it ideal for DIY filter and conversion projects. The larger format media is much easier to control when retrofitting into an existing filter, minimising the risk of media escaping.Despite its larger size, K3+ Advanced Filter Media maintains the standards expected from Evolution Aqua with an impressive total surface area of 800m2 per m3 and a protected surface area of 500m2 per m3. Manufactured in the UK for high quality control and consistency, K3+ will enhance and increase biological filtration thanks to its large surface area for bacteria to colonise.During the extrusion process, Evolution Aqua add a range of minerals, along with magnesium, calcium, enzymes and salt to the raw material that is used to manufacture K3+ Media. The result means that K3+ Advanced Filter 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 also added during the extrusion process, which is dissolved during the cooling process, leaving a rough surface on which bio-film can easily adhere.
