Anyone selling a tempest filter? In Midlands area.

Can anyone recommend a reasonably priced pond vacuum please ?

Does anyone know where I can buy a used second hand Oase pondovac 4 pond vacuum cleaner

Does anyone use a sand filter on their ponds? I’m interested in knowing the benefits from it I’m considering running one in junction with the Kockney koi 5000.
