Big Bamboo,
Sorry for the loss of the fish.
I hope this makes the point for owners that want to use areation how important it is for a good oxygen meter and start up procedures.
Bass Pro has been carring a good quality O2 meter endorsed by Bill Dance for a while. I would suggest everyone that is serious about their pond get one.
Heck if you had $150 fish in an aquarium you would have a test kit for it.
Again, sorry for the loss and I hope everyone takes note on your experience.
