AB+ is for SPS-dominant reef tanks, so it really depends on your coral mix. I have a mixed reef: probably 4 dozen soft corals (zoas, leathers, mushrooms, GSP), around 2 dozen LPS (elegance, duncan, hammer, torch, goniopora, pectinia, favia) and maybe a half dozen SPS (monticap, psammocora) in addition to 6 BTAs and 7-8 rock flower anemones. So my lighting and supplements are geared towards my specific reef requirements.
This is a slightly outdated image, but you can see how my reef is setup (my SPS are maybe halfway down and around 200-225 PAR), with most of my LPS in the 125-175 PAR range and anything down along the bottom around 50-100 PAR. PAR at the surface is somewhere between 550-600.
