Why we love it

Main Highlights

[CRYSTAL CLEAR WATER] - This model is capable of filtering ponds up to 6000 litres and is best used for ornamental and community fish ponds (no Koi). It is an extremely effective flow-through gravity filter which comes complete with 8 foams great for biological and mechanical use. There are 4 coarse designed for catching larger debris and 4 fine for polishing off the water from smaller particles.
[QUALITY ENGINEERING] - The 1,500 lph pump included is of course to the usual high standards expected of Swell's own products and requires minimal maintenance as the strainer casing filters out larger debris too avoid any blockages. Very efficient with its low 25w motor making fish keeping affordable. The pump uses 20mm piping (included) and comes complete with 2 banded hose clips for extra security.
[INTELLIGENT DESIGN] -The kit includes a large UVC of 9w that can be found within the lid (for easy access) that will eradicate green water completely from your pond. Checking the UV light could not be any easier with its UV spy hole. The pump comes with a 10 metre cable and the filter a 4 metre cable.
[EASY MAINTENANCE] - Maintenance is simple with its in-situ filter foam cleaning mechanism which allows you to squeeze the foams free of dirt without even getting your hands wet. The dirty water can then be flushed out of the filter box with the 2 sludge drains found at the bottom of the box. All units come with an instruction manual on how to use.
