Swell Filter Box Premium Kit 25000

Our Swell Premium Box Filter Kit 25000 is a large pond filter set-up perfect for both Koi and goldfish ponds. They are extremely effective flow-through gravity filters that incorporate unique filter foam media for efficient mechanical and biological filtration.

This particular model is capable of filtering ponds up to 25,000 litres and is ideal for wildlife, community, ornamental and Koi ponds. The kit includes an 18W UV clarifier that's designed to eradicate green water. It's built into the lid for easy access.

The filter kit comes with 10 foams: 5 coarse foams designed for catching large debris, and 5 fine foams for catching all but the tiniest debris particles. These foams have a large amount of mechanical and biological filtration capacity. For extra filtration, this model comes complete with two media trays that can be filled with additional biological media such as Alfagrog, more foams, carbon and/or zeolite.

Maintenance couldn't be any easier with this filter thanks to its in-situ filter foam cleaning mechanism. This allows you to squeeze the foams free of muck without ever getting your hands wet. The dirty water can then be flushed out of the filter box via the sludge drain found at its base.

The provided pump has a large strainer cage that allows debris up to 12mm to be pumped into the filter box. This keeps the pump flowing and maintenance to a minimum. The pump is also very efficient, ensuring your pond keeping costs are kept as low as possible. It comes complete with a hosetail adapter that's suitable for use with a variety of pipe sizes (25mm, 32mm & 38mm).
