Why does BRS recommend this?
The Blue Plus bulb is by the hottest selling T5 bulb available, for its crisp blue, that brings out awesome coloration in corals. : ATI has been some of the most sought-after bulbs in the reef aquarium hobby. With their bright crisp colors, ATI are our number one choice when it comes to T5 bulbs. With ATI bulbs you can use a single color on its own or you can mix and match to make the ultimate spectrum.
The ATI Blue Plus T5 HO fluorescent bulb combines the properties of a blue bulb with a True Actinic Blue 03 bulb. Encourages bluing in SPS corals and fluorescence in capable corals. Helps balance out a washed out or yellow hued tank. Works well as a supplement to metal halides or in combination with a 6500K ATI Sun Pro or an ATI AquaBlue Special.
|Bulb Color/Temperature||Actinic, Blue|
|Fluorescent Bulb Wattage||24 watt, 39 watt, 54 watt, 80 watt|
Although we wish we could test each bulb and fixture combination available on the market, unfortunately that isn't possible for us. Each fixture has minor variances in things like wattage and amperage draw. Because of these differences, their respective PAR readings can be different even with the same brand of bulb. :-)
This will vary depending on height and other factors, what reflectors and other impact however under 6-10 inches of tank you can expect high par in the 200-300 range for good SPS growth. at 24" you can expect lower par in the 100 or lower range.
The best combination of bulbs through ATI that we use are the Blue Plus and the Aquablue Special. We typically recommend 2 of each on 6 bulbs. From there you can use the remaining slots for supplemental lighting such as coral plus for more white based light, actinic for a deep blue and purple plus for unique coral colors. Feel free to let us know if you have any further questions!
The bulbs are labeled by the size of fixture. As long as the wattage matches they will work for your fixture! Feel free to let us know if you have any further questions!
