I have a 55 gal tank with about 16 mbuna cichlids which NEVER shows a trace of ammonia or nitrite...even when I go longer than I should without changing water.
I also have a 72 gal tank with 4 small frontosa and a few other small lake tang cichlids which never has ammonia but constantly has a small amount of nitrite.
Both tanks have been up and running for close to a year. What could be going on with the big tank?
