Well I moved it as close to the light fixture as is possible in my aquarium and phosphates are falling. (not fast enough)

Hopefully it comes back. How could I tell if it was completely gone?

It'll turn a nice pretty white color.
And can someone explain how to get it to brighten up? I only see new growth nice and bright when a coral browns out. For the most part anyways

+1

Typically once a coral gets what it needs, the whole piece will color up. I had a piece brown out in the back of my frag tank, once I put it back into a good spot in the DT, it turned bright blue again within a week or two.

Can't say for all sps but my ssc goes brown then bright then brown lol I think in my case its phosphates .

I have a blue mille and Oregon tort that
Went snot brown and are bright now:)

Not sure why exactly but beats white lol

Kind of same topic so not trying to hijack.
So Brad did the base of your SPS kind of brownout under your LEDs? I noticed mine do that and they never did that under MH. Which makes me think there's not enough ummmm I dunno, spread I guess with LED:confused:

No, the LEDs kept the SPS constant from base to tip. Just a slight loss in overall tone. Even at the lower areas of the tank.

Well mine are much different color at the base. Not all, only the really big colonies. Thought it was from lack of light. Dammit I hate testing water.:lol:

some of my colonies are huge, and solid color from bottom to top. But I had 6 units running at 100/100/96, so maybe brighter than yours?

Well I took a really good look and i'm thinking it's just the shade. Tried taking a pic but with a stupid rounded front I just cant get a good pic. I'm just overthinking I guess.
