Thanks for the comments everyone. Yes, there are zero nitrites...or close to that. I had higher levels last Saturday, but returned the damsels that had cycled my tank. I picked up 15 more lbs of live rock, which the lfs
said may start another mini cycle, so to wait a week before fish. I fed the empty tank twice while waiting. The owner of the store said that based on the level of activity with invertebrates...brittle stars, bristle worms, snails and lots of Kenya tree corals that came in on the live rock....my water is good. The gramma has been hiding since I put it into the tank, but the chromis are having a blast exploring!
