Looking at that link, they all look very bleached. How long is your light cycle?

Dusk to dawn (4x54watt T-5) 7:30-8
day lights (4x54watt T-5) 8:30-7

That should be ok right?

My bulbs are as follows

4x ATI Blue+
2x ATI Aquablue special
1x Giessaman Aqua pink
1x Giessaman Pure Actinic

Might be a bit much. I use about 7 hours of daylight, seems to work well. With too much light, they can over oxidize nutrients at the cellular level, causing bleaching. I'd maybe back off a few hours and let them darken up, then reassess from there.

So.....is my dusk to dawn ok? or should I be backing that off as well?

Depends on the intensity of the light, I'm not familiar with T5. I use a single actinic from 8am to 1:30pm, then daylight until 8:30, then back to the actinic until midnight. Works way better for me over my previous 10 or 11 hour daylight cycle. Saves on bulbs too.

This may be a stupid question....but if they were bleached....would I suddenly experience a growth spurt?

The last 2 months or so my other SPS's have been growing by leaps and bounds

Not sure, but I'd guess probably not. And it's possible I'm just not seeing the pics right, but even with the white balance off, you should see some color. The RP, you can see the polyps fine, so I have to assume the tissue is white. It should be red, or under less light, a green tinge. Not white.

I'm sorry to say but I don't see any truly healthy corals in those pictures. Extremely pale and bleached looking corals. Pale colors are from too much light, and/or too little bioload-feedings....

Yes you can experience a tempory growth spurt when corals are put into this environment but soon they stop growing and things go down hill.
