I've used this before, one tip, follow the instructions below. I removed the drain plug on the skimmer and just turned the skimmer down a bit. It foams like crazy, but the skimmer adds the extra air the tank needs during processing. You might not notice much of a difference the first time. day, but by the end of the second day you should see the cyano almost gone. If your aquarium contains a lot of cyanocyanin, vacuum it beforehand. Perform a 20% water change after 48 hours and repeat if your aquarium is really bad.
