I have a Kessil 150 over my 3.7g pico tank. I was curious about how close is to close for acropora. I don't want to burn my coral but I also want it to get enough light to grow. For the last couple days it has sat approx. 8 inches above the coral itself. I moved it today in fear of burning the coral. It is currently sitting about 11 inches above the coral now. Just want to make sure I have everything in the right place. Here is a pic of my tank prior to the light move today.
