SPS Lighting - MH 14K photoperiod?

[sleeri]

Any recommendations on SPS photoperiod for 250W 14K MHs? Not sure this detail matters, but I run DE Phoenix bulbs. Have mixed reef with primarily zoas and SPS. Thanks.

Just curious, are any of you running the new Pheonix 14k Hexarc Bulbs?

I am, at least the box said Hexarc.

Thanks for all the input. I've got a "standard" 75 gallon tank. I've got the Hexarc bulbs as well. Thought those were just the normal 14K phoenix?
