This popular pond filter is a solid and reliable option.
The Green Genie filter has long been a customer favourite and thanks to its classic 'flow through' filter that can serve a up to 3,500 litres (so long as there are no koi). Dirty water enters through the multi-stage pond inlet, passes through filter foams and into a bed of bio-media. Clean water then returns to the pond via the outlet.
Note: Colour of box filter changing from green to black over the course of 2019.
