They changed it a bit but it still works. We have a municipal backwash system that removes chlorine but recycles once a week or at night as needed. If the tank was cleaned the day before I'm still confident that the chlorine is out and safe for the fish. I have some left in my last bottle so it's ready when I'm not home.
