Water quality readings as of this afternoon: 
Ammonia: 0.25 
Nitrate: 0 
Kh: 7 
Calcium: 440 
Phosphate: 0 (undetectable) 
 
I hadn't run any tests for 6 weeks or so and didn't realize that I had ammonia in my tank.  I'm guessing that the tank hasn't stabilized since I added a group of three anthias about a month ago.  I usually only add one fish at a time, but I thought it best to keep the group of anthias together.  The ammonia reading is pretty low, but I'm guessing that I should wait for the ammonia to drop to 0 again before adding a clam?
