I'm still testing out the orbits, with good results thus far. Only have one SPS and one stunner chalice as far as high light needing corals and they are doing fine. Not long enough to know how the growth rate will be. But also keep in mind with the orbit I am using, it is over a 40b which is alot more shallow than alot of peoples tanks AND I got the larger unit, 36-48" for my 36 inch tank rather than the 24-36" inch one so I get more "watts"....
Will keep updating my thread on the orbits as time goes on and report anything, good or bad I find. But so far the tanks colors are awesome and the corals all open and look great. But as X said, only time will tell for sure and they are relatively untested.
