Was this a new addition to the tank?
No. I got the pink as a frag at the swap in December.
do they always look like that? Was the video taken before or after feeding?
They pretty much are always like that. I just feed mysis and F2 pellets, nothing specific for the corals.
Is it just your return and cloosed loop for flow?
Yep. No powerheads, just 12 loclines on a 6600 gph pump and the OR6500 for return from the sump.
When I saw Russ' awesome tank, I didn't see the PE on the same corals I had gotten from him and asked him if there was something wrong with my sps, the reason the PE is so much. He told me it was a good thing and so I told him I'd post a video of the PE and the current in my tank. I will make another vid of the acros and other milles. My tort looks like it is feeding constantly. With all the particulate matter in my tank, maybe they are.
