Not sure. Travis at upscales sold it to me and we thought it looked like an Aussie delicate. It was complete brown with green polyps. Then it started to color up nice with blue tips. It has been growing very well so far.
I have been running the zeo for only 3 months so its a little soon for me to say it does. This tank has been setup for close to 5 months and before I was running bio pellets on the old system. The clam has never really grown much at all since I've owned it.
You closed your Aefw thread and I was wondering how things were doing with that? I have not seen any Aefw in my system for a while now and think they may have subsidized.
Gsp is considered a pest nowadays. That would be like have an aptasia grow out contest...if I could go back in time and never bought that live rock with a tiny square of Gsp things would be so much better.
Looks great. One I would do though is upgrade to a bigger skimmer. I used to have the same skimmer, it's only rated to 120g and that's with a very lightly stock tanked. With your system the sro2000 or even the sro3000 be be better suited.
