Ok so I just opened a container of chemi pure elite for 20 gallon tanks. I've only used this once before, in the nano size for a freshwater tank. I remember opening it and the contend being dry, black, and having a moderate amount of dust when rinsed. I just opened this one, and there was a dark liquid inside, which the bag was soaked in. Some of the beads also have a reddish tint. I literally rinsed it for 3 minutes straight with a TON of crap coming out, the same dark liquid and lots of what I assume is carbon dust. Now it's still producing the same stuff just not as much. Should I not use?
