Pumice stone Filter Media is now being used extensively as an alternative to traditional koi pond filter media in trickle filters and trickle towers .Pumice stone Filter Media is inert and rapidly colonises with beneficial bacteria which help cleanse the pollutants. It is highly porous making it the ideal media for biological filters of all kinds. Efficient biological filtration depends on the media of choice having an adequate specific surface area (SSA), adequate voiding and water retention time. Pumice Stone Filter media has a massive surface area and is therefore ideal in this application. It can be used as a direct replacement to other ceramic based filter media.
Oyster Shells
Oyster Shells have been used for years by Koi professionals to help with the pH of the water and to maintain optimal water conditions and is extensively used in Japan.
Since the Oyster Shells will generally raise the pH level in your water, these should only be used in cases of low pH.
Oyster Shell generally will raise the level of the pH.
For those that ever ever been to Japan, Oyster shell is used extensively by the breeders in Japan, these soluble (soft) shells are used to stabilise the pH.
Oyster shells stabilise the pH / KH-value which prevents pH crash. If the KH value drops to this starts to dissolve the shells until balance is reached again. Nitrifying bacteria also grows on the oyster shell.
NT LABS Zeolite 5kg
Zeolite is commonly used in pond filtration systems to help absorb and remove ammonia and other nitrogenous compounds. Recharging the zeolite helps maintain its effectiveness over time. For best results, use NT Labs Zeolite throughout the year and recharge it regularly. Consider recharging and topping up when water quality begins to decline.
How to use:
Bacteria Home media
Bacteria home is a high-quality filter medium that is made from mineral rock. This porous rock is baked at a very high temperature. It is ideally suited for a bakki shower, but can also be used in other filters.
The microscopic pores immediately ensure a rapid growth of high concentrations of bacteria, which greatly improves the water quality. The bacteria filter harmful substances such as nitrate, nitrite and ammonia from the water.
The material is very porous and slightly rough on the surface, so that the water that is sprayed over it is, as it were, polished. Because colonies of anaerobic (low-oxygen) bacteria can nest in the pores of this filter media, which take care of the conversion of nitrate to nitrogen gas, you could prefer this type of filter media to non-porous filter media.
Two types of bacteria are involved in the aerobic (oxygen-rich) conversion. The Nitrosomonas bacterium converts ammonia into nitrite and the Nitrobacter bacterium then converts nitrite into nitrate. Although nitrate does not immediately pose a health risk to fish, high doses are not desirable. High nitrate levels promote strong algae growth; this mainly occurs in the spring because the bacteria have not yet multiplied sufficiently.
Anaerobic bacteria are used to convert nitrate into nitrogen gas. This process can only take place in the absence of oxygen, i.e. at places in the filter media where little or no oxygen is present and can reach. The first step in this process is the reversal of the nitrification process. Nitrate is converted back into nitrite. The second step of the denitrification is the conversion of nitrite into nitrogen gas. (N2). This gas can then be released without causing any further damage to the environment.
Bacteria Home also provides an increased mineral and redox value. It also brings considerably more oxygen into the water than, for example, aerated bottom drains. Bacteria Home improves your water quality up to 16 times more effectively than aerated underwater filtration.
Black Knight Spawning Brushes
Pack of 2 specially designed soft spawning brushes each brush measures 1.5m by 140mm diameter.
Spawning is made easy with the help of these specially designed brushes. The breeding season is normally from April to July depending on the weather.
Place the Spawning Brushes just below water level, one above the other, at the edge of the pond, this will
encourages your fish to spawn, usually in the early hours.
Spawning takes several hours with the eggs sticking to the brushes.
After spawning, separate the brushes from the broodfish to avoid the eggs being eaten.
Place the brushes in filtered water of the same temperature and the fry will hatch in 3-6 days.
Small fish should be kept separate until they are large enough to be introduced to the pond.
Please Note: These spawning brushes are made from a soft material that won’t harm your fish. DO NOT USE filter brushes for this purpose
Japanese Matting
Japanese Matting, probably one of the best of all the filtration media which is available in the UK today ..
Japanese Matting is extremely inert and easy to service, Japanese Matting is available in sheet form and can be cut to the desired sizes to fit your filter chamber by using an Angle Grinder or better still an ordinary Circular Saw but be careful and wear protective glasses and watch those fingers unlike the fins on our Koi fingers don’t grow again.
Alfagrog
Alfagrog is a porous foamed ceramic material, which is lightweight, strong and inert.
It’s high surface area makes it the natural choice for colonisation by micro-organisms in biological filtration systems resulting in cleaner water.
The Alfagrog range of porous ceramic filter media is made under controlled conditions UK.
Selected clays and raw materials are rapidly sintered at high temperature to produce a foamed ceramic porous mass, which is crushed and sieved to a convenient particle size.
Alfagrog is available in a wide range of sizes giving the end user optimum media surface area in varying water flow rates.
The manufacturing process ensures that no substances are present to adversely affect the health of fish or plants. The material is pH neutral and can be used in both freshwater and marine applications.
Why is it so effective:
The key to effective biological filtration is choosing media with the highest surface area possible to allow beneficial bacteria to colonise and remove waste from the water. Alfagrog has an extremely high surface area by volume compared with other types of filter media on the market.
Alfagrog is very inert and soon colonises with beneficial bacteria. Alfagrog is made of a highly porous material that contains many thousands of tiny pockets in which bacteria can thrive making in an ideal material for biological filters
Its only draw back is its sharp on the hands when cleaning so please wear gloves..
Benefits over other filter media:
Vortex Brushes
Vortex chambers are good for settling out heavy waste but much less efficient with the lightweight particles. Have you noticed that even though you get a lot of waste in the bottom of your vortex, you still find that the subsequent chambers get very dirty too. This is the very fine particles that do not have time to settle in the vortex and so they get drawn through the transfer port into the next chamber.
First, they physically trap the large particles that cannot pass through the close weave of the interlocking filaments. Secondly, the filaments have a static charge that ‘grabs’ any small particles that are flowing by. This charge holds onto the waste until you do your routine cleaning. Thirdly, after you have been using the brushes for a few weeks, the massive surface area of the brushes becomes home to millions of beneficial nitrifying bacteria that will help to purify your water biologically.
