My tank has been cycling for two weeks now. I have a 55 gallon tank with 40 lbs of live rock. About 4 days ago I took some advice and added two shrimp. I have yet to see any ammonia readings. My tank went through a 24 hour period about 2 days ago where the water was foggy and smelled. It has since cleared up and I now have thousand of Copepods. Could have it cycled or should I keep waiting? Are the Copepods a good sign? I didn't check for ammonia until after I added the shrimp.
