Sunsun CPF - 15000 Pond Bio Press Filter with 18W build-in UV Lamp

The CPF series pressure filter is an excellent filter set for the garden pond. It is fully equipped with filter cartridges, and the correct selection and arrangement of the cartridges ensures proper filtration of the pond.

The filter uses multi-stage mechanical and biological filtration.

Mechanical cartridges - coarse-grained bio-sponge (blue) and fine-grained bio-sponge (yellow), which ensure excellent and very thorough purification of water from all mechanical impurities and provide a habitat for nitrifying batteries.

Bio-balls are biological cartridges. Biological filtration is the heart of the entire filtration system. The decomposition of all biological pollutants takes place, such as the decomposition of food residues, dead plant remains, etc. . Biological cartridges have a very large active (filter) surface area. The bio-sponges and bio-balls are an excellent substrate for beneficial nitrifying bacteria, which clean the water of toxic nitrogen compounds (they process toxic NH4 and NO3).

In addition, the UV-C lamp used destroys algae in the water, combats bacteria and parasites dangerous to fish and plants, and eliminates the causes of most diseases - giving the effect of crystal-clear water.

The lamp, works by irradiating the water flowing through it with UV-C rays, which causes the algae cells to die. The UV-C lamp is also effective against bacteria, parasites and protozoa.

The CPF series filters have a self-cleaning function, which means that the filter cartridges are cleaned without having to remove them.  Connect the hose to the third outlet end, switch the filter to the cleaning function and turn the handle located on the filter cover. Dirt that has settled on the sponges is removed from the filter by the backward movement of the water. The dirt does not end up in the pond but can be used, for example, to water the garden.
The self-cleaning function facilitates the operation of the filter and saves valuable time.

Advantages of pressure filters:
- The filter can be partially buried , making it invisible in your garden.
- Unlike normal filters, the water from a pressure filter can flow out, be raised up to 3m above the filter e.g. for a cascade, stream (depending on the pump used).
- The unit combines biological and mechanical filtration and eliminates algae thanks to the built-in UV lamp. Crystal-clear water effect.
- It has an indicator that shows when the filter needs to be cleaned.
- The simple opening system of the filter cover makes maintenance and cleaning easy.
- UV lamp operation indicator.
- The three-stage filtration process ensures maximum filtering quality.
- The unit is designed to be able to maintain a beautiful pond environment.
