We just figured out in my other thread that i have a super low nutrient environment... Thats why every sps coral i have put in the tank has "starved".
Here's the thread:

Ignore the above post...
I did some research on the browning of sps...
In my case, I still have a low-nutrient systen, but the coral can still be brown due to a lack of lighting... The lower level of lighting requires the coral to increase its zooanthelle within its tissue browning it.
That is similar to the reason that they brown out in high nutrient systems, but in a high nutrient enviornment, the zooanthelle increase because there is soo much food for them...
So my upgrade from my nova fixture to my TX5 about 6 days ago should help the coral get its color back...
Ill let you know how it goes though...
But browning aside, its a Green Slimer right??? I just thought the corallites were not as dense on mine as many images I have seen..

Ryan, there are at least two acros being called Green Slimers, you have one of them (probably A. formosa), but there is another that has strongly appressed radials and is probably A. tumida. In Europe it is call Enzman's Acropora and is a vibrant green...that slimes. If you want intense green, try an iron supplement, but be careful, it can push the algaes, as well, but I doubt your system will have that problem..
There is an interesting series of article by Dana Riddle on the Advanced Aquarist site, dealing with coral colours.

Not necessarily. There are quite a few acros that have this bright green colouring and produce copious slime. There is definitely a green A. yongei. The A. tumida, which looks very similar, but has more appressed radials with a plump lip, also has radials of two sizes, while A. yongei has uniform radials with a flairing lip. A. formosa has tubular radials that are not appressed. All have similar growth habits.
I have no idea which one was first marketed as the 'Green Slimer'. In the USA it may well have been A. yongei. For me, there were suddenly many on the market, but the most common in Europe was the A. tumida. In the last 3 years I've seen or kept many neon green corals. I am currently eyeing a bright lime green A. tenuis and a two-toned green A. tenuis. Mind you, the form is quite different than the slimers, but the colours are just as enticing.
