Mr.West, Thanks for your response. I am still hoping to get more feedback on what I might try next. I understand that there is no simple answer to such issues but I know that there are lots of folks on this site that understand and know lots more than myself about pond issues such as mine. Like I said, I know just enough to be dangerous so I would appreciate some feedback from some of the other moderators or pond managers. I am not even sure what to do next so any input others may have sure would be appreciated. I have in the past always recd great advise about other issues on this site so I know this is the place to come for info. Please chime in if you have any ideas. Thanks to all...
