This hits on something I've been thinking a lot about lately, along with my contractor/friend: using the pond water/fish/by-products/all of it to enhance my garden. I grow over twenty types on peppers as well as herbs and other things. I would far prefer to use rainwater or pond water rather than city water. And I want to utilize as much natural products (I make my own big batch of compost every year; things like that, including vermiculture etc.) so anything I can do to tie the pond into the gardens etc. will be highly preferable for me.
