Fish Crazy
I recently got done treating ich in my tank. I lost my two favorite fish, the pictus catfish, to ich, while the others never had any spots. So, while I was treating the tank, I took the old filters out, and put fresh ones in, without the carbon in them as directed. What does the carbon actually do? I was thinking I would just leave these the way they are, and when time to change them again, just add the filters with carbon. I use 4 filter cartridges in my tank at once, as I have two filters in it, taking two cartridges each. Can I just leave these carbon-less filters in until it's time to change them?
What is the purpose of the carbon, anyway?
Thanks.
