Our Fry Food is fed to over 500,000 Koi Fry every year at Cuttlebrook Koi Farm, the UK's leading breeder of Koi Carp. Every fish we produce has been fed this food during their development, giving them the perfect start in life.   Crushing up food to feed your fry? Feeding your fry crushed-up food (even “high protein” diets) can have a detrimental impact on the growth of your Koi fry. Most used feeds on the market contain around 33-40% protein, however, this is inadequate for the needs of developing fry, regularly leading to bent spines, tails, curled-out gill covers, and incorrectly developed fins. Our Fry Food contains 56% protein. High-quality food is a must To avoid any development issues, high-quality fry food is a must! We advise feeding this diet until the fish are at least 3” inches. Even after this stage, a high-quality diet of at least 40% protein is still required to ensure the best growth and development from your fish. Pellet Size Guide As a rule of thumb, a Fry between 0.5-1.5 inches (1-3cm) will eat 0.5-0.8mm Fry Food, and a larger Jumbo Fry between 1.5-2 inches (3-5cm) will eat 0.8-1.2mm Fry Food.

Make Nexus the automatic choice Continuing our long standing reputation for innovation, the Nexus Automatic System now enables Nexus owners to benefit from a fully automated cleaning cycle on their multi award winning Nexus filtration systems. Physically turning ball valves and manually switching pumps on and off will now be a thing of the past thanks to the Nexus Automatic System. All of the key processes that form the cleaning cycle are now controlled automatically with this easy to install kit. Gravity Fed Setups Pump Fed Setups Overview The Nexus Automatic System can be installed on Nexus 220 and320 filters manufactured after 2006, whether on gravity-fed orpump-fed installations.The kit includes a control box which connects up to an automatedwaste valve, airpump control box and an automatic inlet slide plate(for gravity fed models only). Once installed and connected to yourpond pump and mains power the system will carry out cleaningcycles at timed intervals or when pressing the manual clean button.   Cleaning Cycle The Nexus Automatic System will control the cleaning cycle fully automatically. Cleaning is done on a timer, which is factory set to clean once every 3 days, however, this is easily adjustable to fit in with your pond requirements. The Nexus Automatic System will run a cleaning cycle which lasts approximately 10 minutes. Gravity Fed Cleaning Cycle ■ Adjustable timer kicks in to start a cleaning cycle. ■ Control box automatically switches circulating pump off. ■ The water level in the Nexus equalises. ■ Inlet valve closes whilst at the same time air is diverted from the outer bio chamber to the EAZY to clean the media. ■ After the media has been cleaned, the waste valve opens. ■ EAZY is drained to waste and inlet valve opens for a final flush of the EAZY. ■ The waste valve closes. ■ Air is diverted back from the EAZY to the bio chamber. ■ Circulating pump is switched back on. ■ Nexus returns to filtration mode. Pump Fed Cleaning Cycle ■ Adjustable timer kicks in to start a cleaning cycle. ■ Control box automatically switches circulating pump off. ■ The water level in the Nexus equalises ■ Air is diverted from the outer bio-chamber to the Eazy to clean the media. ■ After the media inside the Eazy has been cleaned, the automated waste valve opens. ■ Eazy is drained to waste. ■ The automated waste valve closes. ■ Air is diverted back from the Eazy to the biochamber. ■ Circulating pump is switched back on. ■ Nexus returns to filtration mode.removed if needed with the K1 Micro in place. This added feature is ideal when undertaking further maintenance. The generally accepted practice is that when you keep ornamental fish, whether in a pond or in an aquarium, to keep the water fresh, 10% of the volume of the water in the pond/aquarium should be changed on a weekly basis. With this in mind, we recommend that you set your Nexus Automatic system to run a cleaning cycle so as to exchange water in line with this.general parameters of our ponds is turn over rate. This is the time that it takes for the total volume of the pond to pass through the filter system once. We recommend that for ideal performance a turn over rate of every 2 to 3 hours is found to be best.

Unlike Fluke-Solve Plus, standard Fluke-Solve can be used in a wide range of fish including Koi Carp, Sturgeon and Goldfish. 100g pack - Suitable for treating 25,000L (5,500 gallons) Fluke-Solve is: Easy to use – it dissolves readily without having to use boiling water or solvent Safe for the fish and for other creatures in the pond or aquarium Economical Science based data to confirm the efficacy of the medication. Contains 50% praziquantel Fluke-Solve® contains 50% praziquantel, and its unique rapidly dissolving formulation means you can see it dispersing through the water as soon as you add it to your pond or tank. It successfully treats skin and gill flukes (Monogenean species), eye flukes (Diplostomum species) and intestinal tapeworms, even by immersion, and can be used in a wide range of fish including Koi Carp and Goldfish. It is suitable for both freshwater and marine systems, including in the presence of salt when added as a therapeutic, and is even effective from 3°C. Fluke-Solve® is safe with biofilters and plants, as well as shrimp, snails and frogs, and can even be used to treat parasites on shrimp. Flukes belong to the group of parasites known as  Monogean trematodes. The most common kind affecting pet fish are the Dactylogyrus and Gyrodactylus species. Cestodes or tapeworms are internal parasites which affect a wide variety of fish species including Koi Carp, as well as aquarium fish such as discus.  How to use/dosage  Use at a rate of 4g powder per 1,000 litres (220 gallons) of pond or tank water. Simply take a clean container of the pond or tank water and add the required dosage of Fluke-Solve® to it, then stir. Immediately add this stock solution to the pond or tank, and then rinse out the container with the pond or tank water and add that as well. If necessary, a separate tank can be used to treat the fish for a treatment period of at least 24 hours. Take care to turn off skimmers while it is in use since they will remove the praziquantel from the water, as will modern filtration systems which use carbon derivatives, or some drum filter technologies. The praziquantel in Fluke-Solve® will persist in a pond or tank for at least 3 weeks, so in the case of some egg-laying flukes repeat the initial dose after 3 weeks to ensure the active ingredient is in the water long enough to kill any hatching fluke larvae and break the cycle of infection.

Pre-filter to remove waste & debris The Cetus sieve is a bow screen pre-filter, made using the latest rotational molding technology. With all of its benefits and build quality, it is undoubtedly the best of its kind on the market today, regarding quality and performance! It is designed to efficiently and effectively remove large amounts of mechanical waste from a pond. It can be set-up gravity OR pump fed and has many benefits over the original bow screen technology. Overview The Cetus Sieve is a self-adjusting sieve which can be installed either gravity fed or pump fed. The Cetus Sieve enables your pond water to be filtered of large amounts of waste and debris before the water enters your current filter system. This process is commonly referred to as “pre-filtering”. The Cetus Sieve can also be used as a stand-alone unit to remove leaves and other floating debris from your pond via a surface skimmer. The Cetus Sieve will efficiently and effectively remove large amounts of mechanical waste from your pond. The Cetus Sieve is compatible with all filtration systems, however it is the perfect prefilter for the Evolution Aqua Nexus filter range. For gravity fed systems the Cetus Sieve has a weir which will automatically adjust to the flow rate of your pump. (Max flow rate 18,000 litres/hr) When the Cetus Sieve is used in front of any other biological/mechanical filter the period in between cleaning will be extended. The biological process is improved by the removal of organic matter which would consume oxygen and leach ammonia and other compounds into the water.

This allows water levels within the pond to drop without causing the circulating pump to be starved of water. The Cetus will allow a skimmer or a bottom drain to accept vast amounts of waste without excessive cleaning needed to be carried out. The water must then be pumped to either a normal filter above pond level (Nexus Eazy/Eazy Pod) or to a pressurised filter. If pump fed, the sieve is placed above pond water level and then the exit water is gravity dropped into your main filter. The Cetus sieve is a bow screen pre-filter, suitable for pre-filtration of any biological filter including all pressured filters. It is advised that all pressurised filters be pre-filtered using a Cetus to reduce excessive backwashing and maintenance due to heavy solids.

Complete filtration with UVC A compact member of the Nexus family, the EazyPod Complete is a mechanical and biological filter system for garden ponds up to 10,000 litres. The EazyPod Complete utilises static K1 Micro, which provides enhanced biological benefits, even when using the EazyPod Complete solely as a mechanical waste filter. Available in Grey or Granite Green colours. Overview Unlike the EazyPod and EazyPodAir, the EazyPod Complete benefits from having an integrated 18 Watt UVC built in to the inlet section of the filter. This makes it a complete filter system in one, helping to eradicate green water, therefore delivering crystal clear and healthy water for your fish.

The water then flows around the circumference of the outer chamber of the EazyPod Complete, passing through the stainless steel grill causing many of the larger solids to be filtered out and settle in the base of the outer chamber. This is the first stage of mechanical filtration. As water enters the central chamber, through the stainless steel grill, the fine smaller solids become trapped in the mass of K1 Micro. Bio-films build up on the protected surface area within each piece of media, allowing biological filtration to take place. After passing through the K1 Micro, the clean water then rises and overflows into the inner return pipe and flows back to the pond via the outlet. The EazyPod Complete is incredibly simple to clean. The connected air pump is used during the cleaning cycle to agitate the K1 Micro to free up any debris and waste that has built up within the filter. All EazyPod Complete models are supplied with a 70 litre per minute air pump and accessory kit.

Advanced filtration systems for Koi ponds now with NEW K+Media Evolution Aqua have launched the Nexus320+ and Nexus220+filtration systems. Building on the tried and tested technology that has been ever present in the world renowned Nexus, the team at Evolution Aqua have gone even further to enhance their number one Koi pond filter. The Nexus320+ and Nexus220+ filters now come with a new filter media called K+Media in the moving bed outer chamber for vastly improved biological filtration and faster filter maturation. The new Nexus+ filters are also supplied “auto ready”, with factory fitted fixings already in place, making it even easier to upgrade to the Nexus Automatic Cleaning System.   Maximum pond size: 18,000 litres / 4,000 gallonsRecommended flow rate: 6,000 litres per hourMaximum flow rate: 10,000 litres per hourVolume of water in Nexus: 510 litresAmount of K1 Micro in EAZY: 18 litresAmount of K+Media supplied: 50 litresMaximum amount of K+Media: 150 litres   Maximum pond size: 34,000 litres / 7,500 gallonsRecommended flow rate:11,000 litres per hourMaximum flow rate:13,000 litres per hourVolume of water in Nexus:840 litresAmount of K1 Micro in EAZY:20 litresAmount of K+Media supplied:100 litresMaximum amount of K+Media:300 litres How the Nexus+ Works The Nexus+ filter is an innovative biological and mechanical filter system in one. Water from the pond enters the Nexus+ via the inlet into the inner chamber which works as a vortex allowing larger solids to settle out. The water then passes through Eazy filter, where finer particles are removed at the mechanical stage of filtration, thanks to the static bed of K1 Micro filter media.The mechanically clean water then passes to the outside chamber of the Nexus+ where the new K+Media Moving Bed is located for biological treatment prior to being returned to the pond. At this stage, biological breakdown occurs through different strains of bacteria and filter feeders living on the vast protected surface area of each piece of the K+Media. These bacteria convert Ammonia and Nitrite into less harmful Nitrate. Water then passes through the exit grill into the outlet, returning back to the pond. Nexus+ Dimensions Installing the Nexus+ The Nexus+ MUST be installed on a solid, level base, a minimum of 1.2 metres x 1 metre. Failure to do this will cause irreparable damage to the filter and will therefore invalidate your warranty. GRAVITY-FED INSTALLATIONS By this we mean that your pump is going to be used to return the filtered water to the pond and therefore your filter will be supplied by gravity via a larger diameter pipe. In this situation the water level in the filter will be at the same level as the pond.  PUMP-FED INSTALLATIONS By this we mean that if your pump is going to be used to supply the water to the filter, and the filtered water then returns back into your pond via gravity, i.e. down a waterfall, or through a large diameter pipe, this is referred to as PUMP FED (i.e. the water is fed to the filter using a pump).

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. 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 fishkeeping 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. Do I need an airpump for NexusPlus? Yes, it powers the moving bed biological filter and is also vital to the cleaning process. You need an Evolution Aqua Air Pump 75 for a Nexus 220 and an Air Pump 95 for a Nexus 320. If you increase the amount of media in the outer chamber you may well need a more powerful airpump.

Building on the tried and tested technology that has been ever present in the world renowned Nexus, the team at Evolution Aqua have gone even further to enhance their number one Koi pond filter.The Nexus320+ and Nexus220+ filters now come with a new filter media called K+Media in the moving bed outer chamber for vastly improved biological filtration and faster filter maturation. The new Nexus+ filters are also supplied “auto ready”, with factory fitted fixings already in place, making it even easier to upgrade to the Nexus Automatic Cleaning System.   Maximum pond size: 18,000 litres / 4,000 gallonsRecommended flow rate: 6,000 litres per hourMaximum flow rate: 10,000 litres per hourVolume of water in Nexus: 510 litresAmount of K1 Micro in EAZY: 18 litresAmount of K+Media supplied: 50 litresMaximum amount of K+Media: 150 litres   Maximum pond size: 34,000 litres / 7,500 gallonsRecommended flow rate:11,000 litres per hourMaximum flow rate:13,000 litres per hourVolume of water in Nexus:840 litresAmount of K1 Micro in EAZY:20 litresAmount of K+Media supplied:100 litresMaximum amount of K+Media:300 litres How the Nexus+ Works The Nexus+ filter is an innovative biological and mechanical filter system in one. Water from the pond enters the Nexus+ via the inlet into the inner chamber which works as a vortex allowing larger solids to settle out. The water then passes through Eazy filter, where finer particles are removed at the mechanical stage of filtration, thanks to the static bed of K1 Micro filter media.The mechanically clean water then passes to the outside chamber of the Nexus+ where the new K+Media Moving Bed is located for biological treatment prior to being returned to the pond. At this stage, biological breakdown occurs through different strains of bacteria and filter feeders living on the vast protected surface area of each piece of the K+Media. These bacteria convert Ammonia and Nitrite into less harmful Nitrate. Water then passes through the exit grill into the outlet, returning back to the pond. Nexus+ Dimensions Installing the Nexus+ The Nexus+ MUST be installed on a solid, level base, a minimum of 1.2 metres x 1 metre. Failure to do this will cause irreparable damage to the filter and will therefore invalidate your warranty. GRAVITY-FED INSTALLATIONS By this we mean that your pump is going to be used to return the filtered water to the pond and therefore your filter will be supplied by gravity via a larger diameter pipe. In this situation the water level in the filter will be at the same level as the pond.  PUMP-FED INSTALLATIONS By this we mean that if your pump is going to be used to supply the water to the filter, and the filtered water then returns back into your pond via gravity, i.e. down a waterfall, or through a large diameter pipe, this is referred to as PUMP FED (i.e. the water is fed to the filter using a pump).

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. 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 fishkeeping 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. Do I need an airpump for NexusPlus? Yes, it powers the moving bed biological filter and is also vital to the cleaning process. You need an Evolution Aqua Air Pump 75 for a Nexus 220 and an Air Pump 95 for a Nexus 320. If you increase the amount of media in the outer chamber you may well need a more powerful airpump.

However the Eazypod Air includes an Airpump 70 Kit. How the EazyPod works Water from the pond enters the EazyPod via the inlet and then flows around the circumference of the outer chamber of the EazyPod, passing through the stainless steel grill causing many of the larger solids to be filtered out and settle in the base of the outer chamber. This is the first stage of mechanical filtration. As water enters the central chamber, through the stainless steel grill, the fine smaller solids become trapped in the mass of K1 Micro. Bio-films build up on the protected surface area within each piece of media, allowing biological filtration to take place. After passing through the K1 Micro, the clean water then rises and overflows into the inner return pipe and flows back to the pond via the outlet. The EazyPod is incredibly simple to clean. The connected air pump is used during the cleaning cycle to agitate the K1 Micro to free up any debris and waste that has built up within the filter. A 70 litre per minute air pump is recommended for use during the cycle cleaning. *Only EazyPodAir and EazyPod Complete models are supplied with a 70 litre per minute air pump and accessory kit. Installing the EazyPod PUMP-FED INSTALLATION By this we mean that if your pump is going to be used to supply the water to the filter, and the filtered water then returns back into your pond via gravity, i.e. down a waterfall, or through a large diameter pipe, this is referred to as PUMP FED (i.e. the water is fed to the filter using a pump). GRAVITY-FED INSTALLATION *User modification is required on the EazyPod to enable Gravity Fed installation. By this we mean that your pump is going to be used to return the filtered water to the pond and therefore your filter will be supplied by gravity via a larger diameter pipe. In this situation the water level in the filter will be at the same level as the pond.

Pure Pond is the Award Winning bacterial product that helps to maintain crystal clear and healthy pond water. For best results add the PURE POND balls into a filter bag and place in the biological section of your filter in an area of water flow. 500ml of PURE POND will treat a pond up to 10,000 litres (2,200 UK Gallons). PURE POND are biodegradable balls, crammed full of live bacteria and enzymes that when added to your pond filter get to work breaking down Ammonia and Nitrite, whilst cleaning up organic waste. The bacteria and enzymes are slowly released when they are needed most to address biological issues in the pond that are often the cause of poor clarity. PURE POND balls work particularly well within the Nexus filtration system helping to smooth out any peaks and troughs in the Ammonia / Nitrite cycle. Simply add the balls into you biological chamber, ideally held within a filter bag, where they will agitate alongside the K1 Media. When using PURE POND balls as a maintenance product, especially when added once a month into your filter, the balls will help to maintain crystal clear and healthy water. Please note PURE POND is not intended to clear green water. An appropriate UVC is recommended to clear green water. Bacteria and enzymes delivered in gel-like balls Maintains crystal clear and healthy water Breaks down ammonia and nitrite Cleans up organic waste Reduces filter maintenance and cleaning Ideal for use as a maintenance product Suitable for use in all types of ponds Add to filter for best results
