dang sorry to hear that. I have had numerous AI lights and never had any issues with them. My zoas looked great under my prime but never seemed to thrive under the reefbreederSame here. SPS seems fine up top but struggle down below, but a couple of my favia down low seem to be getting too much light. Only about 3 of my 15 or 20 diff zoa colonies are looking good.
For what its worth the AI spectrum is my absolute favorite. I just don't think the AI prime would be good for a tank deeper than 16-18 inches. And the reliability of those things are garbage. I went through 3x of the Prim 16HD in a 4 year period trying to light my 16g cube. Of course the issues happened a few months out of warranty. One of the blue lights just stopped working on one fixture. The other two had connectivity and controllability issues, one of which could never be solved. I'm done with all AI products even though its my favorite line of light... when they are actually working.
