I am trying to figure out why lighting would work best for my incoming (eventually) Red Sea Reefer 450 tank. One of the issues is the 59 inch length. The tank is only 93 gallons, but it measures 59LX20WX22H. I don not want t spend a fortune on lighting but it seems that I may need to spend a lot more than I anticipated. Max Spec has an LED unit that costs about $900 for their largest fixture. What other options are there in the same price range or less that would cover most of my tank and enable me to keep most types of coral?
