Best T5 combo for my tank ??

If you have only 4 bulb and wish to keep SPS, you are best to use high PAR bulb. I use:

1 Blue +
1 Fiji purple
1 Aquablue special
1 Blue +

Those are 4 bulb with high PAR and I can grown all SPS very well with this. In fact, I had to move the lamp up because my montipora were bleaching a bit because the light was too strong. My blue mush were gray. Now with the light at about 8" from the water top, my mush are blue again and the monti are getting their color back.
