What type of lighting is best?

[Slayer33]

I'm a little confused in the lighting area... my tank is a 60 gallon, 18" tall.

I used to run a 36" Current Orbit IC light but was told this wasn't sufficient... so I supplemented it with a dual 36" T5HO with ATI bulbs... eventually I was told that a quad T5HO is better than the setup with the LED.. so I got rid of the Current Orbit and replaced it with another dual 36" T5HO fixture, and am now running it with 2x Blue Plus, 1 - Coral Plus and 1- Purple Plus. I am also running 2x 36" Aqueon Blue LEDs for nighttime viewing when the T5s are off, but also run them 100% on with the T5s together during the day cycle.

I don't see crazy coral growth but everything is happy (to my knowledge at least)...

I was looking at maybe adding a stronger LED vs the 2x Aqueon Blue LED strips which I think are only rated at 5 watts each. Would that help? or perhaps I need a better combination of t5ho bulbs?

Maybe getting rid of 1 T5HO and replacing it with one of those 165W Mars Aqua LEDs?

Just looking for input.. maybe my quad T5HO lights are more than enough?
