Is there a Coral/Motile Invert Safe Black Sand? CaribbSea Hawaiian, Yes Or No?

[Fish Fan]

I just looked up my order from 2019, and this is the product I used.

What could be helpful is running a big magnet through it first to remove any iron, then rinsing it. But dry sand doesn’t make me flinch either way, you can always add bacteria afterwards.

Thank you!!!

I'm glad I asked, that was NOT what I was talking about. I have this stuff:

But, I definitely have seen the sand you used, and maybe that's just what I'll do.

@Randy Holmes-Farley It looks like this is the sand @Reefer Matt used, and it's hard to argue that his tank wasn't successful. Would you mind taking a look here and see what you think please:

Back in the day…read 2008ish…I ran Caribsea Hawaiian Black. While I can’t comment on chemical make up, I did find it was magnetic however during that time I successfully kept various softies and anemones. I did find it made the tank “appear” dark and when I switched back to white sand, the tank was much more visually appealing to me. Not sure if that’s really any answer to your question or concerns but I wouldn’t hesitate to run it again and given the prevalence we have now with many bright sand dwelling corals, it could make for an excellent contrast.

Thank you for your reply and help!

Not sure if this is helpful or not but the LFS I go to started having heavy metal issues on their 240L tank with black sand and had to switch out the sand to sort their problem.

Thank you, that's helpful for sure

Could I ask, was this a new tank or an old tank? And do you know what sand they used specifically?

Thank you again!

I had this stuff in my 10 gallon nem tank without issue. But that was after it lived a year or so in the sump of my 100 gallon reef. I had issues there but it was more likely me rather than the sand.

I'd probably go and do it again as I liked the dark with the nems and platinum clown. Coulda been a better tank, coulda been worse.

Thank you for sharing!

Just to be 1001% sure, did you use the CaribbSea Hawaiian Black or the Nature's Ocean sand motioned previously?

@Randy Holmes-Farley I'm so sorry, I'm sure you have more important threads to attend to, but if you could please take a look at the Nature's Ocean product, it's claimed to be aragonite, but I thought all black beach sand was lava and would have some metals (though I didn't think that was problem until now). The Nature's Ocean product suggests that it includes trace elements that [dusting off my very rusty Chem minor] would dissociate into metal ions that they bill as essential. Could anything here be of concern?

Thank you very much for you time and help!
