What killed my frogs?

Question

I just refilled my pond that has had frogs in it with city tap water. I filled a little more than 30% of the water that was already there.

Answer 1

YOU!!!!!!!!!!!!!!

Answer 2

Yes, That dust would have done it. It is toxic.

Answer 3

"Jolt" cola is for humans  only, not frogs...Actually, I had that happen with a dozen tadpoles I was raising...and I thought they were the heartiest things ever! I think a sundden dramatic change in the water temp, or chlorine levels can be fatal...sorry for your loss!
