Ron,
Very glad to herar the fish are OK! Soiunds to me that when you say to be "in the know" means to "eat, sleep, drink ponds", means you are certainly one of those in the know.

When I read your statement "I have went through great lengths to control runoff and any possible pollution from finding it's way into the pond"< I thought to my self, This guy REALLY cares about his pond! That is often one of the most labor intensive ways to manage your pond. Some could say that was interferring with mother nature, along with fishing it. Bottom line is that it is your pond and I certainly admire and applaud your obviously diligent effort to keep your water as pristine as possible.
I would personally love to see some pictures of your pond. I absolutely love spring fed waters!
Every pond is different, has been wriiten here many times. Just as true, are that everyone's ideal pond is different along with management strategies. I beleive many of the bells and whistles used in our ponds take away from our learning to truly appreciate many aspects of Mother Nature's work, yet they are often quite beneficial.
