Now that would be odd if I had too little light. I have a 250w bulb and ballast for my 180 that I would consider trying, although I'm really afraid of baking my tank.
I read that about the XM bulbs, this is my last XM bulb, after hearing about the PAR problems i don't want to stick with them. On the other hand though I've been running XMs for awhile now, 400ws on my 230g and 175w on my previous cube, and actually saw a lot of growth and nice colors from them. Still though I'm looking for a new bulb for my 180g project. I'll have to visit Sanay's site to pick out my next bulb choice. I think I've figured out my next two tests; 1) the light, downgrade the reflector for a couple of weeks. Its a cheap test to run, I don't have to spend any money. 2) ORP and Ozone, first part will be testing my ORP and then from there either purchasing a ozonier or not. Any other steps anyone can suggest I try?

The XM 175W 15K does have sucky PAR so I think we might be onto something: http://www.reeflightinginfo.arvixe.c...&Submit=Search Try an Iwasaki 175W 15K, which has the best PAR out of any 175W bulb on an electronic ballast. For a magnetic ballast, go with the AB 13K. For the record, XM bulbs vary widely in terms of PAR output. Their 15Ks generally suck regardless of wattage whereas the XM 250 10K is the PAR king.

So I guess this begs the question about what to do now? Do I switch out the reflector and try to continue with my current bulb for a couple or weeks, or do I order a new bulb and try a new bulb with my luminarc reflector?
An update on the four pieces today; Neon Green Digi - good; polyps out, lots of color on the side that isn't right under the reflector. Less color, and a burnt? tip on the side that is under the reflector. This frag is right on the cusp between being under the reflector and not. Stag - Still looking bleached on the coralites, no polyps Acro - Looking more bleached now, and this time on the top. This coral is almost directly under the MH. Still no polyps out. Cap - Looks a bit more bleached, no polyps. When I go back and look at my previous SPS test batches I noticed two things; 1) I placed all my SPS on the sides of the tank, and I placed them very low. I never moved them, 2) My MH bulb at the time was much older coming to the end of its lifespan.

Green digis require probably the least amount of light of any SPS IME so perhaps this is why it's still doing OK.
I'd get a new Iwasaki 15K bulb and place a small SPS frag right under it as close as possible to the surface.

Well the ORP thing is out for a bit longer. I got my mail and the box with the ORP monitor is well crushed. The monitor is cracked. I've called the company and they are dealing with it.
I'm afraid to put any SPS highter, I think they actually are getting burned by my MH. I just turned my lights on for a few minutes to feed my tank, and the way things are looking, it really looks like a burn. I wish I had a camera to post photos with right now.

Its the same stuff we got from Bow Valley for our 180g. AI used to sell it when I worked there too.
The batwing reflector is up and running, I'm taking photos before and after of the process, then I'll put my MH on for their 5.5 hour run tonight. I'll post some photos later today. I'll also try to see if I can't get some photos of the SPS.
