Traded bit of rock for a 4x65 watt pc fixture by current. Wanting to replace the 4x 54 watt t5ho I'm using now. But what bulbs do I wanna get? There seems be be a wide range of choices and I may get some better growth using different bulbs. Right now I have 2x10,000k and 2x 460nm actinic. I've heard that 6500 helps corals grow as well. So I dunno if I wanna get these bulbs I seen that we're 50/50 -10000/6500. Or what. Also seen some that were 12000/460. Biggest thing is right now I have actinic coming on 2 hrs before 10000 and opposite when they go off. For dusk and dawn effect. Any help?
