I have read a lot about building a koi pond but i am unsure of where to put the skimmer, filter and pump?
Does anyone have a diagram of where to put all the stuff, preferrably the pond would be L shaped. or can you tell me please because videos on youtube etc... dont really say where the filter goes.

Here's an article that I wrote about how to build a koi pond.
Oh and thoughts about skimmers:
