    Lights on a fish only tank is only for viewing purposes. So you can leave them off for a while. Unless you want coraline algae or other algae to grow for tangs and angels to pick on from the rocks.
    What you are experiencing in your tank sounds like new tank sindrome, hence the diatoms on the sand. It will pass when the system stabilises.
