Do I change Carbon in Protein Skimmer?


New member
Should I be doing anything with the carbon (??) in my protein skimmer besides rinsing? I usually rinse with my RO/DI water, but should I be replacing it......if so, how often?

How about the filter media in my canister filter (Eheim pro II)

a protien skimmer has nothing in it-its a chamber full of bubbles, that raises gunk into another chamber...

you may have something different set up, can you take pics?

Swanwillow.....its the "other" chamber that has the black granular (assuming charcoal) filter media...not the bubble chamber.

I just hear that it may be better to do without so it wont collect nitrates....

Can charcoal filter media be cleaned?

Its a Red Sea Prizm skimmer.
