Tank is a bowfront 46, filled it Saturday, its now Thursday, live rock, live sand, power head etc., going to be fish only for now, however not sure down the road but that's the situation now. Parameters testing ok, but then they should I suppose, nothing in the tank to cause anything to spike etc. Salinity is 1.023, Ammonia, Nitrate and Nitrite all zero. PH was long when I had water tested at LFS, 7.4 so purchased something to remedy that. Got my test kit in yesterday and did a test myself later in the day, same thing all zero but PH still low at 78, dosed the tank again. Have tank buffer coming in today from Amazon. Question is this: When is it safe to add a fish, obviously a damsel of some kind, and if its ok, one or two? I'm looking at a blue damsel with yellow fins as I think they are pretty for the tank and when tank is completely cycled out I may keep it or them. What else should I be looking at or just monitor and test, test test?
