Well day 8. No traceable amounts of ammonia, trite, or trates. Hmmm, expected at least some. I know the rock was from other systems as well as some of the water and bought live sand. I suspected the test kit but the nano did have .25 ammonia (star died). I'll keep watching it. No cyano yet either. I guess I shouldn't complain but surely I would get a mini cycle. Do larger systems need time to build up waste or is the mr1 just doing it's job?
