think itd b alrigh to leave the night time lamp off at night (no lights at all at night) as long as the temps are fine? dont have a dimmer yet and my only nighttime light is like a 100 watt bulb for the larger tank and to keep it warm in the winter. i knw they are cheap and i plan on replacing the lower wattage one that died this weekend, but would leaving it off at night suffice in the meantime?
