HOW DOES IT WORK? 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 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.
