I have a question on lighting for my reef tank. I have an all-glass standard 65 gallon (36x18x24) as pictured below...click on thumbnail. Tank is comprised of octocorals,mushrooms,and zoanthids,gsp only.
Right now I have two 175watt 20k xm single end bulbs running 11 hours a day.
I know alot of octocorals reside in shallow water and prefer intense light. Do you consider two 175watt 20k bulbs over the 65 intense?
I do have a pfo 250watt hqi ballast and a aqualine 13k bulb currently not in use. Do you think I would be better off using the 250watt setup on one side and the 20Kxm the other?
Or would you guys suggest I sell the 175watt ballast and bulb and throw on another 250watt aqualine bulb?
Would two 250watt bulbs be overkill?
I just want the corals to be happy,but I want to simulate the light they would get in the ocean.
thanks all! very curious to hear your thoughts.
