A small update just to let folks know what I'm seeing.
So far the lights continue to perform as expected. No problems or issues with the units at all. I am seeing growth on some corals. My Favia, which has been in my tank for about 9 months, has never shown any growth before. It was a frag when I got it, and its not much more than that now. BUT...... for the first time it has grown! It is on the sand in the lowest point in the tank. It now covers the frag plug completely.
I recently picked up red and green Monti frags. The Green is definitely showing growth. The red, not much if any. At the same time I picked up a Chalice frag. It too is showing slow, but unmistakable growth. My Zoas are not fading away, but I can't say they have grown. My Mushrooms, Hairy, Blue and Green striped, are looking good. My Torch, after having been moved around a bit, is also looking healthy.
The GSP, though intitally bleached, is getting its colour back but may not be doing too well. Not sure. This has more to do with other issues as the unaffected area (90%) is looking great and growing.
Water Parameters are spot on as far as I can test for.
Again, I'm very happy with the lights.
