What are these blue spots on my rock?

[Pg513]

Just over two weeks into my cycle and noticed these small blue spots on my rock. Any idea what it may be? Tried searching for an explanation but results were nil. These were dry rock from Marco. Any help is appreciated

Look like coraline to me

I don't know. It's certainly more blue than a purple. I was always under the assumption that coraline came further down the road. Im only 15 days in and still have a good amount of nitrites. I suppose anything is possible.

It sure is a pretty blue.. Following

Some kind of Algae or just discoloration from the chemistry between light and saltwater.
It's to soon to see coralline in your tank.
What are your test results?
What kind of lights do you have?

Like stated above it is to soon for coralline algae yet. I believe it is either some type of algae or the light spectrum is causing the rock to look that way.

Would be interesting to see under the microscope!

Here it is without the blues on the ai prime, only the white:

What type of rock is this? Is it "live rock" or something like Marco rock?

They're Marco.

 

[Sabellafella]

They look like little aliens lookin back at me ha! I think its just some discoloration on the rock. Id give it some time and see if it changes

 

[BossGT911]

its prob. not but, it looks like a wierd sponge

 

[reefwiser]

Dry Marco Rock I would doubt it is sponge. With no other live rock in a new tank it could just be how the LED hits the rock itself.

I suggest just to keep a eye on it but most likely it's nothing.
Your test results look all as they should be for a fairly new tank and your rock is still in the process of maturing.
Check back in a few days and update us on this.

So, I'm betting that one piece of rock came into contact with something blue before coming to you. It's dry rock right? or was... So durring storage, or shipping or whatever it could have come into contact with something blue that transferred to the rock. Have you tried to get it off?

At first I thought it was just the blue LEDS on the rock, but the picture without the blues is pretty telling. Maybe it's paint or something like that.

 

[abruzzo62]

Im thinking its blue plastic from a container it was stored in. Bucket maybe? Or if it definitely wasn't there before, maybe a spot in the rock with a large amount of calcium? Calcium "corrodes" blue, like how copper turns green. Probably wrong but it's possible.

I have the same blue on my rock. Started with dry rock. Tank is 3 months old. Blue lights are turned off for this picture.

 

[isopods]

I have the same thing. I don't have a pick. But that is why I was reading this. What is it? I hope something good.
