Aquarium external filter (Knottingley WF11 0PX)

Sunsun 3000l/h External Canister Filter for Fish Tank Aquarium with UV Flow Control

Used but fully working (I think) haven't used it for a while as now have aquarium with sump. It's been up in the loft and as far as I can remember it was fully working when I last used it but I think the UV might not be working. Comes with instructions and fittings/pipework. Might be of use to someone before it goes down the tip.
