I can put it on the same cycle as my tank lights. They are on 12 hours a day. I hear it is better to have your ref lights on the opposite cycle as your main tank lights, but I also hear it doesnt matter.
The advantages of the reverse light cycle are as follows:
- The growth of algae regulates and buffers PH
- The growth of algae increases oxygen redox potential
- The growth of algae increases available oxygen in the water and reduces CO2 concentration
-The growth of algae removes nitrates, phosphates and some metals
All this in mind, with the lights on reverse of the display, the conditions at night are allowed to improve due to the growth of the algae, allowing time for the fish and other creatures to reap the benefits as well while not in the stress of day lit life.
