Hi everyone! Great to be a newbie but it's also terrifying so we can definitely use your advice on how to best care for our koi and goldfish in these ponds. We purchased a home in the Pittsburgh, PA area with these ponds, and they look pretty murky. We got rid of some of the sludge that was backed up by the waterfall but it still looks very murky and we're concerned for the fish. Any advice on how to clear it out without adding harmful chemicals or removing the fish? There might be about 20 koi and goldfish.
Thank you so much!
