A contained body of water is subject to conditions such as dirt, insects, algae and decomposed vegetation that affect the water clarity and health. A filtration system is needed to balance the ponds ecosystem. This filtration system must match both the power of the pump and the volume of the water garden. All Jebao filters use mechanical and biological filtration. The mechanical filtration process uses foam filters to trap debris. While the biological filtration uses biological ball (bio balls), that have large surface areas used to nurture beneficial bacteria. This beneficial bacteria converts harmful pathogens into useful nitrates. Both types of filtration work together to provide a clearer and healthier pond. The Jebao Bio-filters utilize a dual filtration system consisting of both mechanical (foam filters) and biological (bio balls) processes. This particular Bio-Filter cleans ponds up to 3500 gallons. It is recommended for use with pond pumps capable of pumping water from 2000 to 4000 gallons per hour.

HOW DOES IT WORK?

STAGE 1 - MECHANICAL FILTRATION: Water is pumped into the filter creating the necessary pressure to begin the mechanical filtration stage. Two foam discs collect various sizes of unwanted organic debris encouraging the growth of large numbers of beneficial bacteria which break down harmful pollutants.
STAGE 2 - BIOLOGICAL FILTRATION: At this stage the water passes through the bio-balls at the bottom of the filter. These have a large surface area & provide a habitat for beneficial bacteria to grow which naturally convert the harmful toxins of ammonia & nitrites into useful nitrates to support a healthy pond environment.
STAGE 3 - UV CLARIFICATION: The water which may contain microscopic suspended algae spores passes the UV lamp clumping and killing the spores to give crystal clear water.

WHY This External Pond UV Bio-Filter SO EFFECTIVE?

Water is slowed down as it passes the lamp to increase UV penetration
Quartz glass tube covering the UV lamp permits effective penetration of UV rays.
Ordinary glass cuts this by 90%
UV lamp runs at optimum operating temperature in an enclosed chamber
Water is kept as close as possible to the UV lamp to maximize UV efficiency
Single ended lamps last longer and have higher UV output
