Put a hammer coral in my 3 month old tank last week with 3 heads 2 of the heads are going great and one in not opening up like the other too. All water perimeter are good have it on top of 4" sand bed in a 29 bc with rapid LEDs at 50% with medium water flow. What can be the issue as they all were opened up great on day 2 but since it's really just the 2 heads looking great?
