first when i got my 8ft tank i had just 2 blue 4ft lights on top. but now im getting a new hood for the tank and im thinking if i should get 4 2ft light just to make things more mobile . What do u think.
it depends 8ft tank nice are you going to have a fish only tank or with live rock or a reef that will make your decision on lights if you are going to do a reef I sugest you wait and do your homework on this board before you spend a pennie on lights
