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

I'm with Greg on this one. I have my red planet fairly high up in my tank (probly 6-8" from the surface) under 250W.

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.

I figured that was what the answer was going to be. I've talked to a few people in other places who have their RPs in about the same position as mine under 150W MH and they have good growth and colour (nice mix of red/green.. not all red). Weird. I'll try slowly moving the RP up with the bonsai.
The strange thing is though the RP actually started bleaching in the original spot I had it in the tank, about 6" from the surface (Yes, full story comes out). I started it where it is now and them moved it to the high 6" spot a few weeks later. Yes, I understand that more than just lighting can cause bleaching but it was given a loooong acclimation time and other frags that were added the same day were fine. I moved it to a low light area to recover and now I'm moving it back out into the bright light. It's been in a moderate to high flow/light spot for a several weeks now and colour has come back a bit but still nothing of its former glory. So is colouration only a function of intensity and not intensity+photoperiod?
