how long during the day should the light be left on in my FOWLR tank, just a standard light on top of a 30 gallon tank with just a clown fish in it atm with about 10 punds of live rock? thanks for the help
since there are no photosynthetic animals you really dont have to worry about the photo period. I used to run mine 9hrs, but here lately have only had them running for 4hrs a day
