sps

I’ve got good parameters, flow and lighting, however my sps polyp extension is minimal... fish don’t nip and a few extend decently... also good encrusting not a lot of branching... any ideas? I know most of you will say don’t worry because I have good growth but again curious as to why? Also...

I’m setting up a 10g frag tank for growth on plugs. Any suggestions on light flow and overall set up? I want to be able to grow everything in here.... top shelf acros to zoas. Any suggestions would be very helpful. Thanks!!
