I think it's a bit of a misguided belief that all softies don't require lots of light. I'd say some would definitely thrive under that lighting set-up, but I can confidently say that some of mine (toadstool leathers, zoanthids, palythoas, ricordias) thrive much better under strong lighting.
I have a Tek HO T5 set-up and I think the individual reflectors make all the difference. I don't believe the Nova fixture incorporates individual reflectors....but I could be wrong. In which case, disregard me
I guess it depends on what, exactly, you're trying to keep?
