Thanks Paul.
It's a NPS tank apart from the gorgonian that you point out which is a Pterogorgia citrina, I'm going to add a few more photosynthetic ones around the same area up near the surface, my lights are on 1% power so I don't think I could add them any lower.
So far the successes have been the Diodogorgia Nodulifera, it's definitely grown some and generally has very good PE, I've had this about 5 month so far, the Christmas tree coral(Sphaerella) has had a few issues but it's now inflating more and seems to be bigger than when I got it, I've got a few easy things like a sun coral and a chili coral.
I've had issues with the tunicate spewing it's digestive system up, it's done this twice but it doesn't seem to bad now and not done it for a few month.
Sponges are my biggest concern, I'm not sure how long I can keep them going.
I've got a unidentified NPS gorgonian frag that I believe is a Leptogorgia chilensis, I've had a bit of a struggle with this but I'm hoping it's on its way back, it seems to be anyway.
I've also got a flame scallop that I've had in there for 13 month.
So far I've not lost anything since turning it into a NPS tank but it's only been going as NPS for 5 month I think, a few of the gorgonian have only been in a matter of weeks.
I'm expecting it all to probably end badly but it won't be for lack of effort
