Is this safe to use?

[Robbie_Maxwell]

Hi guys. Im in the process of setting up my first reef tank and have just recieved my dry rock but some of the pieces have some kind of rusty color on them. Im just wondering if its okay to use them? Thanks. 

[SeaFurn]

Do you know what kind of rock it is? Where did you get it from? Have you rinsed it? Does the rusty color come off when scraped?

to Nano-Reef.com.

 

It might be alright; but since it doesn't cover the whole rock, or all of the rocks, I'd be tempted to just break off that section (just to be safe).  However, I wouldn't worry about a little bit of discoloration.

Looks like a fossilized pelvic bone. 😬😯

And his hip replacement has rusted out?

Maybe see if you can scrape off any pieces, if you have a strong magnet it should stick to it if it's some kind of heavy metal.

I’d cure it just to be safe. Some of the dead rock “live rock” can still have crap decaying that may lead to problems down the road. Get a circulation pump and container that will hold the rock and water and let it go through a cycle.

Hi. Thanks for the replies. I think im just gonna scrape it off to be safe. I got it from a shop here in ireland and it didn’t specify what type it was. It was just called ’ocesn rock’. Thanks again. Ill keep you updated on how my set up progresses

Honetly looks more like rock used in FW tanks.  

[Robbie_Maxwell]

What should i do so should i contact the shop? 

[Daniel91]

It looks like dried in diatoms - which it probably isn’t.

Is it just that rock?  How do the rest of them look?

[KMitch]

That’s oddly shaped live rock

That’s what I was thinking too.

Yeah, it's probably not the same stuff that we have access to (certainly not as porous).  However, I assume it's still a calcium carbonate based rock, that's mined out of the ground.  I wouldn't worry too much about it.  Just break off anything that you feel might be suspect.

[Clown79]

It kind of looks like caribsea dry rock. But it also looks like rock used for freshwater.

 

 

Can you take a pic of the other pieces? That may help determining what rock it is.

 

 

Or call the store and they should be able to provide you with the kind of rock and the supplier

Is this the place and rock?

Its listed as ocean rock

The rock in the picture on the website is way more porous like we are used to seeing with rocks used in our reef tanks while his picture looks completely different. 

I wonder if his rock got tossed back in the wrong bin.  🤔

I agree with seabass that it does seem to be calcium carbonate based rock because of the white powdery dust/particles on the OP’s hand in the picture. 

[Robbie_Maxwell]

Ya that’s exactly what i bought. The rest look to be more what i was expecting but still not as porous as the picture. 

[Robbie_Maxwell]

The only reason i went for the ocean rock as opposed to the reef rock was that i dont really like the look of pukani(sorry if I butchered the spelling) which is what i thought was in the the picture. ill ring the shop and make sure i got the right stuff just to be sure. Thanks

[seabass]

I'm pretty sure that it's fine.

[Robbie_Maxwell]

Hopefully it will be. Ill still call just to double check. Thanks for the help

[seabass]

I'm interested in what they will say.  However, their site describes it as, "This material is perfect for providing an alternative, complimentary or the base rock layer for Marine systems".  Most vendors sell less porous rock as base rock.

 

But that doesn't really mean anything except that it might not be the most attractive rock that they sell.  We're covering it with corals anyway, right?  Just create a nice aquascape and it won't matter what the rock itself looks like.

 

BTW, I think it looks fine.

[specore]

Looks like you've got some nice pieces there

The rock you got is more than likely fine.
