I just started up the tank yesterday and was wondering if I should keep the lights off or keep them on. Befor in the pasted, that I had said that the sand that is in the nano came from a 5+ year tank and the live rock is allready cured. The water I put in it was about 5 gal that I got out of another reef tank and the rest of the 5 or 6 gal I put in allready mixed water called blue water. Do I still have to wait for the tank to cycle or can I just dive in. And should I start with fish or coral first?
