Hi I have a 105G frag tank. It’s about six months old. All parameters are good and are stable. So far I’ve added about 10 coral frags in the last month or two. Some seem to do well, some of the sps are growing, but the polyps are not extending. What would be the cause of this? I’ve tried messing with flow, made sure my water is stable, but they’re not extending… could it be lighting? I have 2 xr15 blues, running AB+ template 12 hours a day at 50% intensity. Like I said it’s weird, you can see the coral growth, they’re just not happy and extended. Any tips?
