I have 3 XR30 G3s over my 180G tank. I don't have any demanding corals - just some leathers, zoas, ricordias, etc. One of the lights failed this weekend - will come on for about 10 seconds and then shut off. So I'm in search of a replacement, but I can't see spending a grand on a new Radion for the corals I have. I'm leaning towards the Kessil A360X or XE. Would three of those be adequate for my 6' long x 24" deep tank? I only ran the Radions at 55% max. Or any better recommendations? Thanks!
