I have a "Current" fixture 2x250watt 13k Geissman HQI's and " Current" 4 54watt t-5s. 2 of the t5's are actinic 420 and the other two are 460 actinic.
I am going to be keep mostly SPS corals. I like a real strong blue look in the tank. But dont want to sacrifice par. Kinda strong 20k feel, really blue. The t5s I have now, seem like they have a light color to them as I used to have 10k hqis and the 10k was super strong and a real green look in the tank. I hated that.

What colors would you suggest? I will have many different colored corals in the tank and just want the SPS corals to pop. Thanks

With the 13K Halides go with 4 ATI Blue Plus lamps. Good Color and a lot of additional PAR.
