Direct quote from Big E Rimless 80g Sps
The bulb combo of choice is the same Blue+ and Coral+ for Sps. Your Reefbrites will serve to add more blue aesthetically which is fine. I'd start at about 9-10 inches......I wouldn't go lower than 7-8" once things settle in.
Main 8 bulbs eight hours.............Reefbrites I wouldn't do more than a total of 6 hours mid day. I'd start at 4.
Those Reefbrites XHO can be overkill of that single 450nm range........it's too narrow and can cause problems with colors longer term. This is based on what I've seen on friends Sps tanks that overdue it on number of hours per day. They will also tend to turn rainbow acans and chalices orange.
I would prefer more of a mixed LED from 400-465 for supplementating.
