Bruce I copied my last post and pasted it into the Cecil Envy thread with a brief explaination of what I am trying to accomplish.
The bog filter is a small scale version of what I am planning on doing using with my newly dug 1/10 acre pond. By creating contained wetlands to filter the water for me I should be able to increase my biological capacity without using a well. The biological filter uses a pump, however, low head pumping uses a lot less energy than pumping water up a well. The gravel in the filter traps sediment from the water and provides a place for benefical bacteria to live.
I am still debating using a well for my pond to further increase biological capacity, but I would use a low gpm pump to keep the electric bill reasonable.
