Installed Acan Lord in my 120-gallon reef tank. The coral has grown well with vibrant red and teal polyps. I use moderate blue LEDs and low flow. It’s one of the most visually striking corals I’ve added.

The colors are impressive after a few weeks. I noticed it’s sensitive to light intensity, so I adjusted my LED setup to 100 PAR. It’s hardy and stays healthy with stable water parameters.
