1. Water enters the unit and passes close to a UV (ultraviolet) lamp, which is separated from it by a quartz sleeve. The UV light makes algae clump together so it can be caught the the foam.
2. In-built ‘turbulator’ – the flow of the water through the UVC, created by the product design, increases the unit efficiency by even exposure of the water to the UV light and eliminates the possibility of air locks.
3. Water leaves the UV chamber via a venture, which aerates the water for high oxygen content. Position of the venture in the filter is important - the water is oxygenated before it enters the biomedia, which significantly increases the effectiveness and activity of beneficial bacteria.
4. The water passes through the plastic biomedia where beneficial bacteria cleanse pollutants. The amount of biomedia contained in the filter has been scientifically measured and tested to ensure optimum biological filtration performance and increases in direct proportion to the size of filter/pond to support a greater number of fish.
5. A fine layer of foam traps any remaining solid particles as the water passes up through it.
6. Clear healthy water then passes into the pond.
7. A drain is built in to flush out sludge, which collects at the bottom of the filter. The floor of the filter is sloped so sludge collects around the drain for easy removal.
8. Integral carry handles are positioned on the side of the filter to make the filter easy to lift if maintenance is required.
9. Viewing hatch to observe the internal operation of the filter, in particular whether any maintenance is needed.
