			 I have to replace the 4 HO bulbs in a giesemann infiniti fixture.  It has 2 150 MH lights and 4 T5s.  When you purchase this fixture retail, it comes with 4 actinic bulbs.  From this, I assme all your growth is coming from the light provided by the MH.  Would it be of any benefit to use 2 actinic and 2 of something else?  I can run 3 separate timers - 1 for MH and 2 for the T5s. The tank is 120 gal and 24" deep. I do want to have some diversity in the tank in terms of coral and will have some SPS.  Any suggestions?

			 I do not run any actinics at all ATM. There is no beneficial spectrum from actinics mainly color. What spectrum (k rating) are your MH?

			 I am running 4 - 250w 15k with 4 - KZ New Gens.nice color and decent growth but I don't have any SPS. So maybe try a couple 12k & a couple 15k T5's.
