Brown stuff on Live Rocks

Hey, I am new to this forum, and have been reading alot of the posts here. i am learning alot on saltwater tanks!

I have just started a 46gallon saltwater tank myself, and just last week put in about 47lbs of fiji live rock to cycle my tank. The guy at the LFS store said it was washed and half cured. Now, there is this brown stuff growing all over the rocks, and even spreading onto the sand. Is this normal? cus its making the rocks look really dirty. I'll post pics soon.

Any help would be greatly appreciated! Thanks!

I have something like that on my new saltwater 80 gallon as well, I believe it is just algae and it should pass. What do you have in the tank, do you have a uv sterilizer? Any snails or some type of cleanup crew? I was also told by another member that it could be red slime, but i don't think so, I think it is just a algae phase, it is very ugly though, especially on the sand. I am trying this species of goby that filters sand through its gills, hoping that combined with the uv sterilizer i just put in helps. Hope any of those suggestions help :)

I have just been cycling this tank so there is nothing in there except for the live rocks. I just put in a protein skimmer last nite. I was going to put a clean up crew in there once the tank has finished cycling, and it seems like my tank has not finished cycling yet, ammonia = 0.3 and nitrite = 0.6.

i also called my LFS yesterday cus i was so worried, and the guy told me it was the algae dying off, which is normal, and that i shouldnt do anything cus it'll go away in about 2-3 weeks.

So the brown stuff on my LR are almost gone and i have green algae growing now, but on some of my rocks there is this red 'slimey' stuff, which almost looks sticky. and it seems like its spreading onto my rocks and even my filter and powerhead. they all have this reddish stuff on it. Is this the coraline algae that ive been reading about all the time? Can someone post a pic of what coraline algae looks like?

Has anyone told you what was in your tank yet? the pic that was shone is Coraline algae, but from your description it sounds like you may have an outbreak of ciano bacteria or red slime algae. Corline can come in red or purple and it means that your tank is healthy. some like others don't while other encourage the growth (i personally do) how's your tank coming along?

Sounds like cyano. Try increasing your flow and checking your ro/di water.

I don't have a pen.

Hey Kim,

Did anyone tell you to leave your lights off while cycling your tank. If you do, the red slime algae will die almost over night and you can suck out the dead protein when you do your water change. Remember to do small more frequent water changes while cycling. 10% twice a week untill your levels get in check. Just a thought you probably are already doing!
