Esshup, I'm in the Green Bay area.

All of the algaecides that are rated for pond use, providing they are used according to the label, won't affect the fish at all. Now the part about "used according to the label" is the important part. I had a customer that had an algae problem and wanted to purchase enough algaecide to treat the whole pond for a year. I measured the pond and calculated what he'd need for the rest of the year. I told him how to use it and when to use it. He thought he knew better than I did, and didn't want to keep treating his pond every two weeks. So he put ALL of the algaecide in the pond at the same time. "It's enough to last the year, right?" He killed every fish in his pond.

Using anything incorrectly can lead to bad consequences. Take a human drinking water. It's safe right? And we need to do it every day. Did you know that if a human drinks too much water they can die? So, "safe" is a relative term I guess.
