I've been away all week so sorry about not replying on the LED question. Though it seems like other knowledgeable club members have had similar experiences. Here's another experience:
In this video, the radions are set to 70% intensity:

In this video, the blue and white channels are at 100% at a 20k setting but the lights are almost 2 feet above an 800 Gallon tank:

I just switched to Reef Crystals as well and haven't deviated from my normal dosing schedule yet, good to know though. Test your calcium, if your Calcium is low I would up the Calcium dose and turn off the Alk dosing. The calcium dosing (if needed) should lower the alkalinity in a slow and controlled way, which is what you want. Don't make drastic changes. Also, if your pH is high I would suggest a small daily water change. I've heard but not experienced unstable Mg in the water with high Alk can occur so monitor that as well until the solution is remedied.
