okay so my metal halide bulb just went out. and im a fool for not having an extra on hand. but i was curious how long its safe to leave it with out light? i think its is gonna take a few days for it to be shipped and im gonna check the lfs tomorrow to see if they have a bulb that will fit. but.......... should i panic? ive got an anemone and hammer coral and flower pot coral and an open brain not to men-chin the fishys
