Brian, Thanks again for your help. This is all new to me but I am really fired up about getting started. I received my copy of Sylvia Bernsteins' Aquaponic Gardening from Amazon today and will no doubt get lost in it later tonight.I like your idea about rotating trout into the system over the Winter.I do have a couple of ponds here on the property that will somehow factor in with regards to fish/fishing. HSB seem to good to be true! I am looking for some but there aren't any sources close by. Got me thinking about setting up a small indoor pond system in my shop to raise some. I could stock my own ponds and provide some to others who may be interested in HSB in the local area! Plus I here they are delicious!
