Chemi-Pure Blue nano packet leaves black flakes in water

[testuser]

I just got Chemi-Pure Blue to put in the back of my tank and I noticed that no matter how much I rinse it, there are residual black flakes that come from it. Is this normal? Or does it take a long time for it to dissipate? When is it safe to put into the tank?

Sounds like theres too much crushed up carbon in there. The more you grind it together when rinsing the worse it gets. Maybe try a new bag.

Alright, I'll check the other ones. Sounds like the packaging was smooshed because there's a lot of loose carbon at the bottom of the package itself. Bummer. Especially if more are like this, I'll exchange it. Appreciate you confirming that it was bad quality.
