In a fixture of t5ho's 4x24 in a 26g bow front. What would be the best combination of bulbs to run to give the corals most of what they would need to be healthy?
I would go with 3 ATI Aqua Blue Plus and one Aqua Blue Special. These are great bulbs and have comparable PAR values. So, it is just a matter of personal preference as to the color you want. Two of each is a little white for me. I currently have four Blue Plus and two Blue Specials.
If you talking about the purple bulb that ATI has, they just came out with it to compete with KZ fiji pink bulb. It is suppose to enhance your blues,purples and red pigments in your corals. I would not go with the purple bulb unless you are running more than 4 bulbs. I would stick with two blue+ and two blue specials and that will cover most of what you want to achieve.
Blue plus are attinc the aquablue spec.are a daylight bulb. 3blue plus 1aquablue spec. Is what I think ya are lookin for or 3blueplus and 1purple plus. Purple plus is also a daylight.
