T5 bulb combinations

I hounestly don't think you are going to see any difference in growth rate and you are probably going to get poor coloring. The par on those bulbs are the same. Corals use blue and red spectrum for photsynthesis and you have just added a bunch of green and yellow which corals do not use for photosynthesis very well. if you wanted increased growth you should have just feed more. or increased overall par.
