Thanks for the info Bill. If I understand your reply correctly, in my pond's condition (low alk and hardness) there's a chance I didn't kill everything on the bottom of the food chain!! If that's correct I'm feeling much better about the situation at hand. If I'm have it backwards, then I've basically sterilized the pond.

I've collected a jar of water from arm's depth a bit ago and have it sitting on the dock in the sun. I dont see much in it, a particle here and there. Once I see the sample start taking on some color, I'll be adding 1/2 gallon of AquaVet bacteria/enzymes to try to help boost the ecology again.
