My rock had been in tank since saturday late afternoon. Is it time for the first water change? The Sg= 1.025-26
Also: Can I add new sand on top of the LIVE sand provided or do I need to remove it and place it on top of the new?
I am getting Special Grade Reef (Seaflor brand 1-1.7 mm grain).
what are the amonia levels?
N2 and N3 ??
they are what you want to watch on a new tank.
if Amonia is going up then change the water....
