Fish tank no pump or filter

Would anyone be getting rid of a pump and or filter for a pond for free as I am trying to get life back into our school pond as the children love it! Thank you in advance walsall / Wolverhampton area?

Looking for a filter for a 10000 liter pond stocked with koi close to wakefield area

Anyone have a smaller external filter (150L minimum) they’d swap for some bogwood/accessories? Happy to collect. Thank you

Will swap for a momotaro bakki shower but doubt anyone will have one lol
