live rock or coral

[seabassi]

hello , a month ago I purchased a piece of live rock? from the the LFS in the live rock bin, it looked like a piece of coral ( thats why I bought it) there was nothing on it, now all of a sudden it is turning burgundy color and looks a little furry, can this possibly be a piece of coral? i did notice a few weeks ago it has a few feather dusters on it , any ideas
Thanks

The rock in the ocean is dead coral, and that's what you have. The color you are seeing is algae and probably some cyano if you are just starting to cycle your tank. Maybe some coraline algae, hard to say from the descriptors but it isn't living coral.

Do you have a picture of the rock ?

Hi , the tank is 3 months old and this piece is the only one that has that color, just thought it was odd and looks like a brain?
Thank You

 

[Sniperhank]

There is no pic attached.

 

[Keithhjs]

Ah I see in your profile. That is a skeleton of a brain coral with algae or cyano building up on it

perfect thank you, so is that algae good or bad?

 

[Keithhjs]

If its a hard algae it's coraline and good. If its slimy its Cyanobacteria and sign of most likely too much nutrients and needs to be remedied.

ok I will put my hand in there now and feel it, also I do not have a protein skimmer, and a fluval 404 canister I know its wrong, but can't find a sump to fit under my stand 36x18 ( don't yell) LOL I am working on that I have a 65 gallon tank with 50 lb of live rock, 3 blue/green chromis, 1 yellow tang 1 blenny 1 goby 1 dottieback
thats all I have in the tank, all is well and clear and healthy, except this ? ,, any Ideas thanks

 

[Sniperhank]

A canister can be fine if you maintain it properly. The cyano is coming from nutrient issues, which might mean it is building up nitrates and possible over feeding.

 

[seabassi]

my levels are perfect
I just did a test
and my, LFS checked yesterday and that was good, but I think I am feeding too much, also just put my hand on that rock, it seems hard, but there is some of that on the sand?
Thanks
Again

Search Cyanobacteria see if that's what it looks like

 

[seabassi]

it is about the same color, but it feels hard and not slime, most people on the forum thinks its that, but every bit of info helps
thanks

 

[Reeffanman]

Does it come off like dust or does it come off in sheets

 

[seabassi]

live rock/ coral

no, I rubbed it with my finger in the tank and nothing came off, pretty solid?
any idea's
thanks
Frank

 

[Reeffanman]

Possibly coraline. It comes in many different colours
