I currently am running two 120W, 55 LED Apollo fixtures over a custom five foot 90 gallon tank (60" x 18" x 21", l x w x h). I'm not convinced it's enough light. I have a third fixture....do you think I could add it and not be too much light? And to clarify, these are older Apollos that are not adjustable.
What do you think?
