Hi my fixture only uses one size bulb so now I need to find which kind I want. I found two. I am not sure which would give me the bright noon sun look. I know that 21w (2) is for a deep 45g but I thought I might add another single lamp to the tank if I find the 42w is to low. I thought I could keep this fixture on the tank top and not have it raised until I can get the PAR to measure whats what with my tank. The 96w I am using now is to bright. Please advise Thanks
