Biological filtration is the action of bacteria in the tank breaking down dangerous ammonia, converting them to nitrites, and then the nitrites to the less toxic nitrates. Nitrates can be harmful to many invertebrates in high concentrations.
Bio Balls are used for biological filtration. The main advantage of bio balls over other biological media is that the surfaces are impossible to clog up (when used with a pre-filter). The reason is simple: the gabs of space within a bio ball is large and anything that can clog it up would already have been filtered by the pre-filter (such as filter wool, sponge etc). This is the reason why water filtration should always pass through mechanical filtration (pre-filter) before biological filtration.
Bio filtration is a chamber containing living bacteria to capture and biologically degrade nitrogens in ponds. Bio filtration is required to break down ammonia into nitrite and nitrite into nitrate.
This is the preferred system used on larger ponds, its biggest disadvantage is that it needs to be built into your pond at the beginning and is not an easy job to retro fit to an existing pond. The filter you build must be specifically designed to work with a gravity feed and the filter must be set at a height so the water level in it is the same as the water level in your pond. Depending on the type of pond you have you may have to dig the filter in, to achieve this.
External gravity filters: (Gravity return system)
External gravity filters have some advantages over built in systems as they do not need to be built in, are portable for ease of maintenance and must be set to gravity to gravity to return to the pond and thus the level inside the filter will be higher than the pond water level.
Sand filters are used as a step in the water treatment process of water purification.
UltraZap sand filters are made with woven fibreglass and are superior in construction and designed specifically with Koi keeping in mind. The easy access lid is located at the top of the filter for ease of use and for open backwashing.
Pressure testing done on UltraZap sand filters have shown to have passed the standard 4000 cycle test and exceeded 26 750 cycles.
Bead filters are closed (pressure) vessels filled with thousands of plastic beads. These beads are very close together and form a layer through which the water is forced by a pump. As a result, the dirt particles stick in the beads. If the filters are used for some time, the biofilm (the sticky layer) around the beads becomes thicker, so that finer and finer dirt is caught.
We at Ultra Zap aim to offer you the client all the resources you need to ensure your hobby of keeping koi, is exciting and hassle free.
Ultra Zap has a “seasoned” and imaginative team. Since 1990, when Mike and Alan started trading from their small ZoZo hut, they have helped clients grow their passion of Koi keeping by supplying high quality products. With the addition of Keelin and Garth we have a well-rounded enthusiastic team. Though our methods are complex, our goal is simple: we want to help you keep healthy ponds.
Our proven track record speaks for itself. A hobbyist knows that in order to maintain a pond with a healthy environment and clear water for your fish, Ultra Zap products should be your first choice.
We pride ourselves that we are always willing to expand our range of equipment, further more fabricating many “one off’s” for our valued clients. Even though we do not sell directly to the public, feel free to email for any advice and we shall put you in contact with a Koi Store or landscaper in your area.
Our appreciation goes out to our loyal clients and with who’s support have helped us grow from strength to strength and it is our aim to continue growing our recognized brand within the industry.
