I've finished the three day course and I understand I'm now supposed to use charcoal?
I have done a 40% water change. I have a little canister filter I have filled with charcoal and added in. I was planning on doing another 40% change tomorrow and leaving the extra filter in there for a few days.
I've never used charcoal before -- do I just leave it in there and forget about it? Or do I change it for fresh stuff in a day or two? How long should I leave it for? How many water changes should I do?
I've got a few snails I missed before I dosed that still seem active and I'm keeping an eye on ammonia levels.
