Aquarium Photoperiod

By December 20, 2012

Follow me on:

Your new aquarium light didn't come with a tag saying when to turn it on and off. Now you are wondering; is 8 hours enough, 12 hours too much? How long should you leave the lights on your tank? You'll find the answer to that question and others in the Reader FAQ.
