I had a nem die and send my amoneia level thru the roof. I've done several water changes and it's still high, I was told tonight to use carbon but I don't have a reactor. I was gonna use a old canister filter but it has quit working. my question is could i take a filter media bag and put carbon in it and place it in one of the fw hang on filters instead of the filter cartage and it do the same thing? As long as water flow is getting thru the carbon it would work right?
