What would you recommend for my photoperiod? What do Red Planets like?

I would lengthen you photo period until you get the colors you want. I just set up a cube with a 150w halide only, and I've thrown in a few SPS as an experiment. If they don't do well then it will become an LPS tank. I've started out at a 10 hour photo period, I assume I'll have to go longer for SPS. Time will tell.
