The blue wont hurt your fish. Without Co2 only run 2 lights. Personally I would remove the actinic blues and the 10000K bulbs and get 2 either 8000K, 6700K, or 9325K bulbs. I personally didn't like the whiteness the 10000K gave off but its a matter of personal preference. The bulbs you have will work just fine. The blue will not benefit your plants much at all. Do not run just those in there
