Hey wonder if any has any advice? Few of my corals don't seem as happy as they used to be but most are thriving. Attached a couple of pics and wondering of it could be a flow or light issue. They were happy a month ago but take a look at pics let me know? The xenia has really retracted and even closed under the blue light after sunset. I run an hour sunrise sunset and 8 hours at 75%
