I have 4 80w T5s (aquablue and blue+), each overdriven to about 100watts on icecap 430s. These are my primary lighting, and I run MHs for ~4 hours in the evening for added punch. Mushrooms do NOT like this much light, but everything else seems quite happy. I can't speak too much about acros (just added a few recently), but montipora, zoas, xenia, frogspawn, etc., are thriving under this setup.
