Rinsing Carbon

[fishguy449]

The instructions state to rinse the activated carbon under tap water until it is clear of dust. Doesn't the tap water contaminate the carbon and partially defeat it's purpose? I am going to use the carbon after a treatment of flatworm exit.

A small amount of tap water is not going to appreciably contaminate it, since there is not that much that will bind to the carbon in tap water. I use tap water to rinse it. But if you want to rinse in DI water, that is certainly fine and possibly better.
