The blue+ will pop your color. When I had my lps tank going, I used a 6 bulb t5 fixture. 4 bulbs ran all the time (2 blue+, a daylight blend and an actinic / purple), and I'd turn on two more blue+ when I had company.
Maybe you t5 the can chime in here. What bulb would do what LED's struggle to? I've read that LEDs struggle to produce true uv and other parts in the spectrum a lot of corals need. I'll be mounting two kessils in a ati fixture and gutting all but two bulbs. I was thinking I would run the two a350's along with a blue+ and possibly a atinic. But maybe I would be better off with a purple plus and atinic? Or even two atinics?
