Ok, so a few days ago I cleaned and "reset" my 5gal. I had really dirty water, and the gravel just trapped a bunch of food that would hit the floor. Now the milky-white water is starting to come back. I did a search and learned that it's just ammonia-eating bacteria, and it should go away.
I'm just wondering what I can do to make it go away faster. Remove a fish temporarily? I have some stuff called "cycle"....think that would help or hurt?
