Calling Zoanthid Experts!

I have some bleaching, polyp extension isn't very good, growth is moderate, etc. Although oddly I am getting good growth on some of the more challenging morphs. Flow is provided by a MJ600 on the "return", and an MJ900. There is a MJ400 powering a PhosBan reactor, but it obviously isn't really providing much flow. I have a Koralia 2 laying around I could put in there, but I think that might blast the water right out of the tank. I'll toss it in today sometime and see what happens. I have some carbon running passively in the overflow too.

I agree with what you say on the T5s. For bulbs I was thinking UVL 454, UVL Super Actinic, KZ Fiji Purple, and maybe KZ Coral Light II (New Gen)...? However, the Fishneedit fixtures come with bulbs so I was going to pick three 20K and one "pink". I have a handful of other bulbs hanging out in my fish room I can mess around with too.
