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

[ScubaSteve]

Currently I am running a 150W Coralife Aqualight Pro (150W 14K Pheonix + 2-65W UVL Actinics) over my 40g cube-ish tank. I keep mostly SPS with zoas and a couple of LPS. There is, without a doubt, a lot of coral in this tank.

Aside from the odd bad-day-on-the-reef, everything is pretty happy in the tank and everybody has nice polyp extension. There are a couple of SPS colonies (namely a red planet, what I believe to be a tricolour valida, a purple bonsai and purple/blue mystery acro) that just don't quite get the colours that I think they should. While the bonsai is slowly starting to get it's greens back, all of 'em are more on the brown side, particularly the areas that should be purple. I also feel that my growth could be a bit better on some of the other colonies.

The bonsai is was recently moved to about 4" from the surface and is starting to colour up now that it's there, the rest of them are all probably 10" or so from the surface. With the bonsai starting to colour up now that it's being blasted with light it's making me wonder if I am giving all of the colonies enough light...

Currently, my actinics are on at 8:30 am and off at 6:30 pm and MH is on from 10 am to 5 pm.

First of all, who has a Red Planet and how far do you have it from what kind of light? I've been reading many different opinions on this coral and it's placement.

Would you recommend increasing my photoperiod at all with my current set-up?
