Pineapple brain trouble i think

[chrisbahn2002]

i have a pineapple brain that has been struggling, it began turning reddish brown about 2 weeks ago and i moved it to a low lit area of the tank. the green began to come back but then turned to a dark green and reddish brown on the edges. tank PH is between 8.0-8.2, ammonia 0-0.25, nitrite 0-0.25, nitrate 0ish more yellow then anything. calcium is 480. i pulled it out during some rearranging and i caught a wif and about passed out. it smells like rotten eggs. i thinking the worst that it is dead but i want to check with you folks to see what the deal is.

If it stinks then you probably have a dead sponge on it, how long have you had it? What's your alkalinity? Pics would help, so would posting this in the LPS forum since this is the coral propagation forum.
