Pond BIO Pressure Filter SUNSUN CPF-5000 11W UV (CPF-5000 11W UV)

SUNSUN CPF-5000 11W UV Pressure Filter for Ponds

The SUNSUN CPF-5000 is a compact pressure filter designed for small ponds, decorative ponds, and fish tanks where it is important to maintain clean and clear water. The unit is equipped with an 11 W UV-C lamp, which helps reduce the growth of algae responsible for green water. This model supports a flow rate of up to 8,000 l/h, has a filter chamber capacity of 20 liters, and is compatible with hoses measuring 20, 25, 32, and 38 mm in diameter. The filter, with a screen area of 12 m², is designed for fish ponds with a volume of up to 4 m³ and decorative ponds without fish with a volume of up to 8 m³, providing effective mechanical, biological, and UV-C filtration in a single unit. The pump required to operate the filter is not included in the set; it must be purchased separately.

Multi-stage filtration for better water quality

The CPF-5000 filter combines mechanical and biological filtration, effectively removing contaminants from the pond. The filter cartridges trap fine suspended particles, sediments, and organic debris that could otherwise reduce water clarity. At the same time, they provide a habitat for beneficial bacteria responsible for the natural breakdown of organic compounds. This makes it easier to maintain the biological balance in the pond and create suitable conditions for fish and plants.

The 11W UV-C lamp helps combat green water

The built-in 11 W UV-C sterilizer supports the filter’s operation by limiting the growth of algae floating in the water column. Ultraviolet radiation causes the algae to clump together into larger clusters, which are then captured by the filtration system. As a result, the water remains clearer, and the problem of green water is minimized. Combining the UV-C lamp with mechanical and biological filtration achieves a more comprehensive purification effect than using any single method alone.

Convenient Operation and Aesthetic Installation

The filter’s pressurized design allows it to be partially concealed along the edge of the pond, helping to maintain the garden’s aesthetic appeal. The model is equipped with a practical filter cartridge cleaning system and a clogging indicator, which makes it easy to monitor the unit’s operation. The purified water can be pumped into small cascades, streams, or other decorative features located above the filter level.
