Color Combination for T5 Bulbs
 

I currently have two T5 Deep Blue SolarMax HO 108 watt 48" fixtures over my 55G tank, and I am wishing to upgrade the four bulbs over my tank to best help my corals grow and bring out the most colors. I have two Deep Blue Daylight (10KK) bulbs in one fixture, one pink Wave Point "Red Wave" bulb and one Deep Blue Actinic bulb.

At the time I am not growing any SPS corals (and I may never add any) but I do have a BTA, LPS corals, and soft corals.

Also, I've had the tank since last December so when will I need to replace my Daylight bulbs? What is the average life of a bulb before it begins to dim?

Thanks

T5 is usually 6-8 months.

I'd reccomended ATI bulbs. 2 blue+, 1 coral+, 1 purple+
