Think I would know this by now, but my new tank 265 gallon, has only been up for a little over a week. I added about 75 lbs of cured rock and another 75 dead clean base rock. I also added Caribsea pink live sand at 140 lbs. I have yet to see any spike. This morning I have 0,0,0, ammonia, nitrites, nitrate. I've been ghost feeding mysis, and brine..really only a couple of times but, thought I should see some numbers. Normal?
