I am going to be moving and turning my 29gal. into a zoanthid frag tank, until I can upgrade my lighting and tank size. My question is how far down from the top of the water should I put my two levels of eggcrate, for zoanthids?
I was talking to, what I call my personal fish man at my lfs and said most all of thier sps to well underneath thier vho's. phurst they are 50/50 pc's that I have.
The other thing to think of is how long the SPS are at the LFS. They may live under the VHOs but not thrive.
For example, I have a monti cap frag that a friend brought to a meeting for someone else. When that person didn't show up he gave it to me just to see what would happen. It was at the top of my tank under my PC lights. I have had it for a few months and though it is still alive it has not grown. I am anxious to see how it does under my new Solaris fixture.
My zoas were fine no matter where they were under the lights. My torch, Euphyllia sp, the same genus as frogspawn liked to be about halfway up. I haven't had my Solaris long enough yet to know how everything is going to respond.

I'd ditch the 50/50 and just use all 6700K bulbs, the tank won't have an aesthetically pleasing hint of blue anymore but you'll get better growth.
Yeah, almost all "SPS" will do just fine under VHO bulbs if you feed the tank regularly. But again, you'd potentially lose some of that typical "reef tank aesthetic" because many species will drop their colorful refraction pigments - they'll be brown, but still quite healthy and successful.
