The CombiClear 4000 UV + Pump - SuperFish is a complete 4-in-1 underwater filter system for ponds up to a maximum of 4,000 liters. Pump, UV-C, filter media and fountain are combined in one compact unit that is placed directly on the bottom of the pond. This means that no extensive filter system is needed next to the pond and the technology remains largely out of sight.
The built-in pump has a maximum capacity of 1,950 liters per hour and a power of 26 watts. In addition, the CombiClear 4000 features an integrated 7-watt UV-C unit. The pond water is guided through various filter materials and can then flow back into the pond via the included fountain.
Thanks to the simple installation, the CombiClear 4000 is mainly suitable for smaller to medium-sized ornamental ponds where you want to take care of filtration, water circulation and a decorative fountain with one device.
Complete 4-in-1 pond system
The CombiClear 4000 combines four important functions in one device: water circulation, UV-C treatment, filtration and a fountain.
This means that you do not need to install a pond pump, filter and UV-C device separately. For a compact pond, this saves not only space, but also a large number of hoses and connections.
The installation is therefore particularly easy. Place the CombiClear in a stable position on the bottom of the pond, mount and adjust the desired fountain spray head and connect the system.
For ponds up to a maximum of 4,000 liters
SuperFish specifies the CombiClear 4000 for ponds with a maximum volume of 4,000 liters.
However, the actual required filter capacity also depends on the conditions in the pond. Think of the amount of fish, the number of aquatic plants, the amount of sunlight, the water temperature and the amount of organic waste.
In a heavily stocked fish pond, a larger filter system may be necessary. The CombiClear 4000 is mainly well suited for compact ornamental ponds where a simple, integrated filter solution is desired.
Powerful pump of 1,950 liters per hour
In the CombiClear 4000, a pond pump with a maximum capacity of 1,950 liters per hour is integrated.
The pump has a power of 26 watts and a maximum lift height of 1.9 meters. This means that the 4000 version has considerably more capacity than the smaller CombiClear 2000.
The pump ensures the complete water circulation through the system. Pond water is drawn in, guided through the filter media and UV-C unit and then fed back into the pond.
The water flow can be adjusted, so that the operation of the fountain and water circulation can be tailored to the situation in the pond.
Integrated 7 watt UV-C
The CombiClear 4000 is equipped with a built-in 7 watt UV-C unit.
UV-C is used to tackle suspended algae in the passing pond water. These microscopically small algae can make the pond water green and cloudy.
During use, the water flows past the UV-C unit. The treated suspended algae can then be more easily captured by the filter system.
The UV-C thus complements the mechanical and biological filtration. It is therefore not the only filter component in the CombiClear, but works together with the available filter media.
Filter sponge, activated carbon and CrystalMax
Inside the filter chamber, various types of filter media are combined. The CombiClear 4000 is supplied with filter sponge, activated carbon and CrystalMax.
The filter sponge mainly provides mechanical filtration. Dirt particles that are carried with the water remain in the sponge material.
CrystalMax offers a surface on which beneficial bacteria can develop and thus supports the biological filtration of the pond water.
Activated carbon forms an additional filter step and can adsorb various dissolved substances from the passing water.
By combining several types of filter media, one compact unit can perform several filter functions.
Including adjustable fountain
In addition to filtration and water circulation, the CombiClear 4000 also has a decorative function. The system is supplied with a fountain set with various spray heads.
The fountain is height adjustable and can be tilted up to approximately 15 degrees. The latter is especially practical when the bottom of the pond is not completely flat. By tilting the fountain slightly, the spray head can still be set straight.
The water flow and fountain height are also adjustable. This way you can adapt the water feature to the size and appearance of the pond.
Moving water not only gives a decorative effect, but also provides extra movement on the water surface.
Extra connection for a waterfall
Do you want to connect a small waterfall or other water ornament in addition to the fountain? This has also been taken into account in the design.
The CombiClear features an extra connection for a waterfall. A portion of the water flow can thus be guided to a separate water feature.
Keep in mind that the maximum capacity of 1,950 l/h is the total pump capacity. When the water flow is divided over multiple outlets, less capacity is available per outlet.
Compact dimensions
Despite the higher capacity, the CombiClear 4000 has the same compact dimensions as the CombiClear 2000.
The unit measures approximately 31 x 23 x 12 cm.
This means that the filter takes up relatively little space on the bottom of the pond. This is especially handy with smaller ponds, where a large filter element can quickly take up a lot of space.
A stable base ensures that the CombiClear can be placed firmly on the bottom. The large handle makes it easier to remove the device from the pond for maintenance.
10 meter power cable
The CombiClear 4000 is supplied with a 10 meter long power cable.
This generous cable length gives more freedom in determining the position of the filter in the pond. You therefore do not need an electrical connection directly next to the pond.
Always use electrical pond equipment in combination with a suitable and safe outdoor installation.
Easy maintenance
Because the CombiClear is placed completely underwater, the device must be removed from the pond for extensive maintenance. The large handle makes this easier.
Regularly check the filter sponge for accumulated dirt. When the sponge becomes saturated, the water flow decreases. This can eventually become visible because the fountain becomes less powerful.
At the same time, check the pump and rotor for leaves, string algae, sludge and limescale.
For the CombiClear 2000 and 4000, a special CombiClear Filter Media Set 2000-4000 is available. This contains replacement filter media that are tailored to the filter system.
Maintenance of the UV-C
The UV-C part also needs to be checked and maintained periodically.
Limescale and dirt on the quartz glass around the UV-C lamp reduce the amount of UV-C radiation that reaches the passing water. It is therefore important to keep the quartz glass clean.
Always switch off the device completely and remove the plug from the socket before the CombiClear is opened or maintained. A switched-on UV-C lamp must never be looked at directly.
Simple solution for compact ponds
The SuperFish CombiClear 4000 UV + Pump is an interesting choice when you want to filter a pond up to 4,000 liters without installing several separate devices.
With one compact unit, you have a 1,950 l/h pump, 7 watt UV-C, mechanical and biological filter media and an adjustable fountain. In addition, an extra connection is present with which, for example, a small waterfall can be fed.
The combination of compact dimensions, simple placement and multiple functions makes the CombiClear 4000 particularly suitable for ornamental ponds where little space is available for external pond technology.
