We have recently moved into a house that has a good sized pond. It's really healthy - it's full of frogspawn we've seen a frog and a newt this week already. I am terrified I am going to somehow kill it. It has a few different plants (no idea what any of them are), a few wee blobs of algae and loads and loads of those reedy things around the edges. The water is pretty clear - you can see down about a foot into the pond. It's fed by the rain barrel to keep the water level topped up, and the whole area around the edge is pretty boggy - the previous owners had the whole garden quite wild.
Will it pretty much look after itself or do I need to do anything? Skim off bits of leaves from the surface? Keep an eye on the plants to stop it getting overgrown? Anything else I don't know about?
