STAGE 1 - MECHANICAL FILTRATION: Water is pumped into the filter creating the necessary pressure to begin the mechanical filtration stage. Three foam discs collect various sizes of unwanted organic debris encouraging the growth of large numbers of benificial 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 supporty 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 crytal clear water.


WHY ARE Aqua Nova 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 maximise UV efficiency


Single ended lamps last longer and have higher UV output.


UVC Lamp replacement information: Correct procedure must be followed when installing the UV lamp. To avoid damage to the quartz sleeve, if you are having difficulty with installation, contact us for assistance.


Filter foam maintenance. The filter/UVC unit must work dirty to preserve the bacteria. If foams are blocked, remove & wash only in a bucket of non-chlorinated water (e.g. pond water). The foams will often shrink. The unit still functions but you can restore to original size by passing the foam over steam from boiling water with care.
