So i have a 90g with a 48 inch 3 bulb catalina fixture raised 2.5 inches off the lid. I run two bulbs that came from catlina a 10K and 6,500. Since I have moved the fish to this tank with the new lighting only the colors on my roseline barbs look good. My lemon tetras, black neons, pearl gouramis, and Laetacara araguaiae colors aren't popping like they used too and the whole tank has that kind of hospital green/yellow hue to it. Is there a good bulb I can run in the third spot to help bring out the color but not affect the algae potential or a bulb I can replace one of the other two with? I run CO2 and the fish are thriving.
