Just to be sure, cut a green chunk and put it in a bucket of natural water, If it doesn't cause a problem to the coloration, use it. Or toss a couple of minnows in after 4 or 5 days and check on how they do.

It's not about the fish. It's about the pond. Take care of the pond and the fish will be fine. PB subscriber since before it was in color.
