Just started a tank cycle with the One and Only and a clown fish. I have had the bottle for a few months, not refrigerated, but at a temperature of around 76 degrees. The use by date is March 2013. When I added the One and Only, it came out cloudy like I saw on the video but then it quickly looked like white snow moving around the tank. Just wondering if this is normal or if the bottle I added was not good.
