Good job!
I learned long ago that good filtering was important if you (and the fish) want to enjoy the pond . My current filter on my tiny barrel pond has an out of the tank, media filter with an ultra-violet light. The pump pumps 600 gal an hour which enables me to have the filter quite far away (behind the fence). There is also a large cement building block in the bottom which gives the fish a place to hide and makes for a good plant stand.
When I build my Koi pond, I will take your advice.
