We have recently bought a house which has a clearly once much loved but now neglected pond. It's a kidney shape with a liner and has a waterfall with pump and filter system. The electrics to the pump and filter don't look safe and it would be my preference to remove it. I want to keep the pond as a wildlife pond but don't know where to start.
The pond water is pretty murky and there is a layer of muck on the bottom but I have seen tadpoles and water boatmen in there today so there is obviously life thriving in there. So....
Do we need the pump/filter system with a wildlife pond?
Should we dredge the bottom or is the muck down there good for the wildlife (I don't want to upset anything currently living in there)
Can anyone recommend anywhere to get a grate to cover the pond that is submerged just under the water level as we have a 2 year old so want to make it safe?
What else do I need to know? I'm clueless!
