In my experience pale corals are in a defensive mode to excessive light by expelling some of the zooxantelae plus trying to reflect more ilumination.

I agree. Well said.

I would pull the phosban since a slightly higher PO4 level will help darken corals and also expirment with shorter photoperiods.

I agree also with the defensive mode,just seems kind of strange to me to be missing the one color.I've tried the less photo period with the 400's was down to 4 hrs for a few months and got alot of browning and Ph swings
Now i'm running 7 hrs on the 250's and 12hrs vho attinic.could drop to 6 hrs and see what happens.
Also i'll see if i can get some updated pics of my corals.

whatever it is, my tank is full of it. everything is the deepest, richest, greenest green i've ever seen (especially several different pink and blue millies ). it's a new system, just transferred from a 50bb to a 3x3 with sandbed. lights are 4x175w reeflux12K in luminarcs and i just added 4 superactinic t5s driven by an icecap (mostly in anticipation of dropping the iwasaki15s back in once things stabilize and can handle it). phosphate is 0.01 (hanna + rowa) and nitrates are still up between 5-7. i'm hoping once i get the nitrates under control the real colors will come in. i've had good pinks and blues before with a single 250w RF12K, and even though i'm running 175ws now, being in 4 luminarcs butted together over a 3x3, it is really quite bright.

I know the green you speak of with the pink milli's.mine have done that, i assume when there not happy.also i've seen that as a inbetween color before they change.Infact i have deepwater acro that will do that shade of green if go to long with out a water change,then back to blue again.

Well just thought i would give an update,As a last ditch effort i pulled a bunch of grape algea out of my sump.while i thought my PE was great, now its pretty awsome after 2 days and no other changes.Funny thing is, i have had 2 wild colonys for about 2yrs now, that have done nothing,no growth no real PE,But they have it now.So i'm wondering if the grape algea is what is stunting my greens.I'm starting to notice alittle more,but could be from other changes.

I have great greens. I use 400W 20K XM with a par of 128.

Taking out the caleurpa (sp?) was a great move. I have read that they release something that is toxic to SPS.
