Posts like this are my favorite item on the forum. It's great to know what others think when it comes to overall philosophy of pond management. It's also great when people document happenings in their pond. All of you newbies or lurkers take note! You can make a great contribution to this forum just by taking notes and writing down observations. Norm makes a great contribution to this forum through his knowledge and vision, but even if he just took notes like he does, this alone would help everybody out.
