Tank odor- help? [I moved my newest post up here because it is more relevant and better in general than the first.] I put some fish food into a little pantyhose sack. When the part the fish food is in is balled up, it's about the size of a small bouncy ball you'd get out of a vending machine (sorry, I don't know how else to describe it). It's hanging over the side of my tank and it's being used as an ammonia source for cycling. I think I put too much, because my room smells horrible. You can also smell it when you walk into my house (which is a trailer, so it's easy to smell anything in the house). I'm wondering if it's the ammonia, and what I can do to get the odor to go away. My dad just said something about the house smells sour, and I'm afraid I'm going to get in trouble if I don't get rid of the smell. D: What is it that's making my tank smell this way, and how do I get rid of the stench? Thank in advance! ETA: And real quick- when I rub my finger on the inside of the tank, it feels dusty. Does that mean anything?
