Pond Filters

Jebao: The CBF pressurised UV pond-filter range includes Jebao CBF 8000 with 11W UV and Jebao CBF 15000 with 36W UV, along with CBF 4000, 6000 and 12000 models for different pond sizes.

Jebao CBF filters combine mechanical filtration, biological filtration and an integrated UV clarifier. Selected models also include back-flush cleaning and are suitable for installations where filtered water must return under pressure to a waterfall or elevated outlet.

SunSun / Grech: Popular pressurised UV filters include SunSun Grech CPF-2500, CPF-5000, CPF-10000, CPF-15000, CPF-20000 and CPF-30000.

For compact pond installations, the SunSun CUF 6011 Pond Filter provides another option in the range.

Oase: Premium pond filtration options include the Oase BioPress Set 4000, along with BioPress Set 6000 and 10000 models for larger installations.

Large Pond Options: Higher-capacity systems such as the SunSun Grech CPF-50000 and larger Jebao / Oase models are available for ponds requiring higher filtration capacity, subject to stock availability.

Pond volume: Select a filter rated for at least the actual pond volume. Avoid choosing a system that is only just sufficient, especially when the pond contains many fish.

Fish load: Koi and heavily stocked ornamental ponds produce substantially more waste than lightly stocked decorative ponds, so additional filtration capacity is usually beneficial.

Sunlight exposure: Ponds exposed to strong sunlight can experience more suspended algae and green water. A pond filter with an appropriately sized integrated UV clarifier can help control free-floating algae.

Mechanical filtration: Foam and other mechanical filter media trap suspended debris before the water returns to the pond.

Biological filtration: Biological media provides surface area for beneficial bacteria that help process ammonia and nitrite produced by fish and organic waste.

UV filtration: UV clarifiers expose circulating water to ultraviolet light and are useful for reducing suspended green-water algae. UV does not replace mechanical or biological filtration.

Pump compatibility: Match the pond pump flow rate to the filter’s recommended operating range. Excessive flow can reduce filtration effectiveness or exceed the filter’s rated capacity.

Plan for real pond conditions: Manufacturer pond-volume ratings can vary according to sunlight and stocking level. For heavily stocked koi ponds or ponds in full sun, selecting a larger filter than the nominal pond volume is usually the safer choice.
