Aquarium Advice Freak
For two weeks I've been having trouble with nitrites and nitrates for some unknown reason. The tank has been up and running for 8 mo. I pwc'd everyday for a week. I think I vacuumed the substrate too much because the tank seemed to go into a minicycle. Today, after an emergency morning pwc finally the nitrites are gone!
Does anyone know what can turn a tank around like this so suddenly. I'd be interested to hear advise.
