My 20 gallon has a stock top lid with a light. What options do I have as to lighting? I am considering advancing to corals, currently have a FOWLR tank. I think I read something about watts per gallon and distance between the light and the water... but didn't quite grasp the concept. Could someone give me more insight to this please?
Thanks.
Thanks.
