I don't know the answer to your question but someone on here will soon. However I looked on your profile and I am guessing that if we knew more about you and your body of water the questions could be answered better. How big is your pond, how old is it, how deep, what are the reasons you are killing all of your fish, etc.

Hopefully a real expert will chime in soon.
