Evolution Aqua K+ Floating Media 25L
Available in bags of 25 litres and 50 litres
New advanced filtration media
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.
Class leading surface area
K+Media is 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 extrude K+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 its large, protected surface area, but also answers the problem of how to speed up the time taken to mature your filter.
Minerals added for faster filter maturation
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 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.
Increased surface area
With a new shape and profile, K+Media has also been designed to have an increased and class leading surface area, meaning an overall surface area of 1,350m2 per m3. More importantly for biological filtration, the protected surface area of K+Media is 1,025m2 per m3. This allows a stable bio-film to form and remain intact when used in moving bed biological filtration, as in the new Nexus+.
Stable bio-film development
The shape of K+Media optimises the amount of “quiet zones” within the media where a stable bio-film can develop. Whilst K+Media keeps 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 as Rotifers and Vorticella to thrive. This is an additional benefit as competitor media do not have such “quiet zones” that 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 been proven filtration technology for many years in the fish keeping hobby.
Use with PURE Pond products
Evolution Aqua also recommend using K+Media in combination with the PURE Pond and PURE+ Filter Start Gel to boost bacteria levels which in turn will stick to the media and speed up the maturation process even more.

How Much is Delivery?Free Deliveries
ALL orders over £49.00 qualify for free delivery at Complete Koi & Aquatics. Depending on the size and weight of the product this can range from next day delivery, to a 5 working day delivery.
*This does not include livestock.
*This may exclude certain UK addresses
Next Day Tracked Deliveries - £5.99
Customers will have the option to pay £5.99 for next day tracked delivery by APC. In these instances, automated messages will be sent out via text OR email allocating a timeslot for delivery. APC are the ONLY licenced livestock couriers in the UK
Pallet Drop Deliveries (Large/Fragile Items i.e. Fish Tanks)
Large and fragile items such as fish tanks, which cannot be fulfilled by standard courier companies will be palletised and delivered within the pallet network. Pallet deliveries are undertaken by large vehicles where the pallet will be delivered curb-side for customers to process.
Pallet deliveries are usually free of charge to mainland UK. Customers outside mainland UK will be contacted prior to processing your order should further charges apply.
Due to the nature of the pallet network, expected delivery dates are only estimated. We endeavour to ask drivers to call customers in advance but this doesn't always happen. Should a delivery fall outside of your expected date, Complete Koi and Aquatics will not be liable for this. Once a palletised consignment has been despatched, it cannot be cancelled or refunded.
ALL fish purchased via Complete Koi & Aquatics will also be sent out via APC as a next-day, non-conveyable, wet delivery with an AM time slot. Due to the health of the fish we are unable to offer an afternoon delivery. The fish are packed with plenty of oxygen and water to get them through the night. They are kept in the secure caged part of the vans and are handled with care. When the fish arrive, carefully float the bags in the pond to acclimatise them. Generally, we recommend floating the bags for around 30 minutes. After this we then recommend introducing small amounts of pond water to the bag for a further 15 minutes, prior to introducing them to their new home.
Royal Mail Deliveries - £3.99
Orders under £49.00 will also have the option to purchase our standard Royal Mail delivery service. This costs £3.99 and generally takes 2-3 working days.
