 Few manufacturers in the world have put as much effort into designing a flexible and good value range of multi-bay filters suitable for the Koi pond as Cloverleaf, and how refreshing to not only know that they are British but to acknowledge they offer first class technical support to customers/end users.
Key features of this well constructed compact "CL" range are the options of the filters being pump or gravity feed (meaning below ground), whilst meanwhile being very simple to maintain.
