When we moved into our home in 2007 we inherited a 1,800 gal pond with some cool fish! Over the past years my pond has suffered. I've tried just about anything to keep this new found hobby going. Killing over 40 fish over the past 7 years is getting old. I need help!!!!! The plants don't grow worth anything like they use to when we first moved here. I am willing to learn from you all.
