Hi, as above this is very off topic, so bear with me...
We're removing our pond for a revamp of the garden, more child friendly, so the pond equipment is no longer required.
There's a lot of different kit, including a large multi-stage filtration tank, lots of large bore pipework, 3 pumps, 2 small, one large, another smaller filter, two UV lamp filters and some other pipes and fittings.
Also the pond is currently built with a glass dam wall, so you can see the fish swimming about, very cool!
So, if anyone is interested I can send some specifics, everything available to set up your own koi carp pond, even some fish if required!
