If you have nothing in the tank then its not necessary to have the lights on. Just asking for algae issues lol

I keep the lights on for about 10 hours or a bit less non my cube just for my fish and for me.

I have a mix of many different saltwater fish amongst my tanks, but I love my Tangs most of all.

sure...months from now. all running the lights now will do is cause macro
algae to cover the rock that coralline might grow on later.

the coralline won't die and with powerful lighting the coralline will grow on everything.

would you rather have coralline algae or nuisance type algaes caused by excess nuitrients from a freshly cycled or cycling system?

coralline doesn't grow that fast. it's probably cyano. see if you can wipe it off with your finger. also, coralline algae and anything else that's alive on the live rock you bought will live with just ambient lighting from the window or house lights. i have more coralline algae in my sump which is lit by curly-Q energy saver bulbs than in the display lit by halides.

unless you have corals in the tank, i would turn the lights on for a few hours a day, so you can enjoy the tank.
