I am currently in the process of curing ich out of my tank of 20 gallons that had 2 goldfish and a rubber lip. I did attempt to save the fish but in left with only one goldfish and it’s looking bleak. I did take out the filter cartridge when I began medicating the tank and fish for ich. Once I have successfully cured the ich from my tank am I able to reuse this catridge? It’s a carbon filter.
