I have had my pond for nearly six months now. In that time i have recognized a certain amount of tools that a pond owner can not be without...
#1 pond boss
#2 Wallet (must be loaded at all times) & (keep away from wife)
#3 Shot gun (must be loaded at all times) & (keep away from wife)
#4Traps (keep away from wife)
#5 elbow grease

I may have left out a few but I believe that the tools stated above and determination you can conquer any pond problem..Just remember..when it comes to game wardens and wives what they don't know wont hurt them, but if they find out it may hurt you......
