How-Dee from Montana,

I have a small 4x8 foot concrete pond. Plants and gold fish live and thrive in this pond all summer. During the winter, I let the freeze over. The pond plants and fish survive in the bottom, which dosen't freeze. Green algae forms in the pond. Last fall, I noticed a redish color on the upper sides of the concrete. This spring I found all of the gold fish frozen in the ice. After draining the pond, I noticed dried-up redish gunk on the pond sides.............

Could this be a killer type of a red algae? Help.

Different sorts of info. Possibly helpful:

You might want to check with your local agricultural extension office.
