Bill D and others.... This help is awesome! Your questions are easy I think. I would feed if I had to and I would be more than willing harvest some fish.

Here is a concern I have about building structure now. I'm only 1/2 full. Could any structure I throw in affect the ability to later seal the pond if needed? I do not think I have a bad leak but I don't know. It has been going up a little each day.

Also, do I have to plan a stocking plan with some plants around the edges? Do they go hand in hand or are the plants mostly for decoration?

What about the general microscopic life? It has been suggested that I get 55 gallons from a neighboring pond to put in mine to start the little bugs.
