I was reading and article about keeping the tank clean in order to keep down ammonium production. It mentioned a word that i have never heard but i guess i have seen in my own tank. "Mulm" only described as the stuff that piles up on the bottom due to fish waste and biological stuff. My question is, how do you tell mulm from typical beneficial bacterial colonies? If i am not cleaning my tank well enough will this lead to poor plant growth? What do you guys do other then a light vacuuming of the bottom to keep it clean? Should we dig the sucker into the substrate where we can to get the brown stuff out of there? If i look at my tank up close there is about an inch of brown material below the top layer, is this good? bad? Should i run my hand through the tank to stir up all the junk when i do my water changes?
Thanks...
