Quick question about carbon. I recently had ick in my tank and I had to remove the carbon from my canister because the carbon will remove the medication from the water. So I was thinking, if I have carbon in my canister and I do a water change and add water conditioner, will it remove that the conditioner and make my water toxic because it didnt remove the chlorine and such? What if I added prime to lower nitrates or something, will the carbon take it out of the water before it can do its job? You get what I am asking. I have been running without carbon for 6 days n tank is still crystal clear (Ich has been gone for 2 day), tank is healthier than ever.
