So I use orphek light bars only on my aquarium and am starting to think maybe my lights are the reason i get no growth or color. I do get very tiny growth out of my hammer coral but still very dull colors. I have 3 12 inch bars over a 15 gallon cube running at around 40% each. Does anyone know what might be wrong or what signs I should know if my lighting is right? for example every how many days should my glass be covered with algae. Thank you and i’d appreciate any comments!
