Is My Live Rock Dying?

[cloudyrain]

hi pple,

my LR has been changing colour ever since i bought it from a LFS abt 6 weeks ago (grey to green/purple/maroon).... but recently, a few white patches on one of my LR started spreading.... is my LR dying?

attached is a pic of my LR.... pleas advise....

does it have anything to do with the worsening algae problem (diatom bloom??) that i'm having now?

(btw, the tank is 2ft n almost 2mths old.... got one clarkii, one anemone, one tubeworm n one damsel)

white patches means that the coraline algae died and left a white patch is it? i'm not sure but i think that when corlaine dies, they leave a white patch where they use to be..

Dun think you can do much about it...... well9 maybe you can ask some gurus for help)

does the algae dying mean that the LR will not be "live" anymore? or the beneficial microrganisms inside the LR will still continue to live despite the algae dying?

one more thing, i've been noticing frequent, powderish "secretions" from my LRs, is this normal? what is happening?

[clowntrigger]

Coraline algae need calcium to grow, just take note. There might be lots of reason why it die, but it you can provide its need, that is High calcium, good water condition, in no time the coraline algae should grow back.

Something wrong with my eyesight - I refer to the first pic that is being posted. Looks more like debris-covered LR to me ..

[shiraz]

yea clowntrigger is right... calcium is needed... try dosing kalk.. might help. but do u know y your coraline algae suddenly disappeared?... hmmm maybe water params or temp?

[cloudyrain]

hmmm.... the temperature always constant at 29degC... got any other more natural methods other than adding kalk? is kalk expensive?

n my previous qn, wat are those powderish "secretions" from my LRs?????
