Last night I did a water change and before I did it I change my ASM g3 collection cup. I notice it was really back. I did not think much of it until about 2 hours after the water change I check it out and it was like a black power stuff getting suck up. The only thing I can think of is the carbon in the cannaster filter. Is this the case? If so can it hurt the tank?
Can carbon leak out and end up in the tank and skimmer?
