So, I was the person who suggested the CVS one, and yes, it works wonders, but that doesn't mean you can't do the other things suggested.
I was BIG on moss before I found the humidifier but my girl hates EVERYTHING having to do with water. (If I put damp moss in one of her hides, she would refuse to go near it). She was fine with little bits of moss around the tank until she got a piece of it stuck in her nostril, then she just- well, you get the point.
Different things work for different people.
