I’m picking up my first corals tomorrow, a small frag of Space Invader Chalice and a small frag of Toxic Cyphastrea. I’m running my Aqua Knight on my 10 gallon cube at channel 1-50%, channel 2-50%, and channel 3-13%. 1 and 2 are blues and 3 is the whites. Using my iPhone with the Photone app with a DIY paper diffuser and a vacuum sealed bag, I was reading 200 at the top rock and around 100 on the sand. I had the app set to blue/white LED. It was hard to get my phone exactly where I wanted it, but this give me a rough idea. Looked like the two coming tomorrow are going low on the rocks!
