These sets have proven to be a real hit and this one is no different, containing a pond pump and box filter that are perfectly suited to ponds with a volume of up to 6,000 litres (1,320 gallons). The powerful 3,000lph pond pump pulls the dirty pond water (including solids up to 6mm) through its strainer cage and then pushes it to the filter. This size of box filter is the most popular we sell as, at last, there is a professional multi-chamber option available that everyone can afford. This set contains the following components (please click links below for more information): • PondXpert UltraFlow 3000 pond pump • PondXpert Filtobox 6000 flow-through filter * Saving made when compared to buying items separately.
