I don't believe flourite is usually capped. It does make a mess even after rinsing. I have some in four of my tanks. Usually if I'm just setti ng up a tank, I run the filter full bast with some cheap filter floss for a few days, then change the floss to whatever I'm going to use to cycle the tank. The floss will be very dirty at this point. I do rinse the flourite A LOT before adding it to the tank. The cloudiness shouldn't hurt fish, and it does go away over time. Hope that helps!
