this is what happen to my tank to all my lps coral died what's left is my leather coral. I used the same carbon product I baught at petco and it nukes my tank in just 24hrs. they should not sell that kind of product anymore
Ya its pretty terrible. Hoping..that this at least gets picked up youtubers or something for a wider reach. Anyone reading this, willing to mail out some samples of my container or the entire thing.

This is quite disturbing to say the least.

It appears that copper is commonly used in conjunction with activated carbon for a variety of reasons. Here is one example:

Cu Catalyst Activated Carbon

Copper-Driven Deodorization and Antimicrobial Action
Cu is a catalytic activated carbon functionalized with nano-dispersed copper particles. By activating copper ions, the material promotes deodorizing and antimicrobial effects through the catalytic activation of oxygen in air or water. Supported on high-grade coconut shell activated carbon, it effectively decomposes odorants and inhibits microbial growth. With low toxicity and abundant availability, copper offers a safe and eco-friendly solution.

Features:
Odor Decomposition - Copper ions activate oxygen molecules, enabling the oxidative breakdown of malodorous compounds such as ammonia, hydrogen sulfide, and acetaldehyde. Deodorizing performance is both rapid and long-lasting.

High Efficiency - The nanoscale dispersion of copper enhances catalytic activity, ensuring efficient odor and microbial reduction even at low dosage levels.

Sustained Effectiveness - Cu catalyst carbon provides long-term stability, reducing replacement frequency and maintenance needs. Its deodorizing and antimicrobial effects persist over extended periods.

Our copper catalytic activated carbon is activated carbon with copper impregnated in nanoparticle state into a high-quality coconut shell activated carbon with excellent adsorption action. It possesses deodorizing function due to copper.


Apparently another way is to prepare activated carbon with something like CuCl2.

Yikes!

Wanted to note that no response was ever recived from Petco. Considering pursuing a lawsuit but haven't dont enough research yet.

I called my petco when I had this issue and they put a stop hold on the product initially and took it off the shelves - went back for something different a week later and saw it back on the shelves. The employee I talked to said she had heard from multiple people before me having the same issue with the coconut carbon specifically too. It's a shame that they really just don't care about the animals or the effect their products have on those animals at all.

For what it's worth, this was an obviously AI generated reply that unfortunately isn't really germane to the OP's problem of PetCo carbon possibly (seemingly likely) containing copper. The general feeling of the forum at large is that AI generated replies are frowned upon to say the least. Here's a post from the owner of R2R asking that AI replies be reported as such. Just an FYI 🙂


From the above link:
"If you see someone answering a bunch of questions that you believe are AI Generated please report them. We’ll check it out, run a little “diagnostics” and confirm or deny it. Then we will ask the member to please not use AI to answer questions, plain and simple. There are enough AI engines and websites for people to use. We don’t need or want R2R to be one of those.

Real people, real answers is our new motto! Lol!"


I hope this is helpful 🙂

@Fish Fan you have made a terrible mistake. To be clear, I absolutely did not use AI in any way shape or form.

This very unfortunate situation is a subject that concerns the reefing community and me greatly. In my research I discovered that GAC is commonly treated with different forms of copper (and other products) to enhance various characteristics. I came across one of many companies that manufacture such products, UES (Ueda Environmental Solutions) Co., Ltd., and quoted several passages from one of their webpage's. As I commonly do in my posts, for reference, I provided a link to that very webpage in my post! You may want to review that webpage.

My post goes directly to the OP as it strengthens the validity of the stated hypothesis, and also provides a plausible way that such a terrible thing could happen through a simple product mix-up.

With all due respect, you owe me an apology sir!

I will apologize if I offended you in any way, but I don't believe that was not an AI generated post, and all I was doing was pointing out what the owner of the forum said about using AI 🙂

Thank you for your reply!

Wow, I’m a stand up guy, and please don’t accuse me of lying to you. If I used AI I would humbly apologize, and make sure it never happen again.

To alleviate any lingering doubt, this is a screenshot of the manufactures webpage link I provided that clearly shows I quoted the example product datasheet word for word.

If you think this is an AI violation, I will tell you directly it is not, and I strongly disagree with your misguided opinion. I have researched and worked with datasheets my entire life. If you think my writing resembles AI, then I'm not sure if I should be flattered or offended.

You may disagree, but I believe the “quoted manufacture supplied information” provides simple fact based background and foundation to the situation, and is of interest to a significant subset of the reefing community. Up until my post, I don’t think it was well known that copper infused granular activated carbon is a common product. Now we are all well informed that it is, and we all know exactly why the product exists.

I agree with the R2R AI policy, but I also believe people fulfilling the roll of AI police should exercise caution.

Like many many other R2R members and ex-members, I'm becoming less inclined to contribute to R2R scientific discussions. All to often well intentioned posts, especially from newer members, become cases of "No Good Deed Goes Unpunished", or intense scorched earth debates. You make a simple post and the next thing you know, you find yourself in a position analogous to defending your PhD dissertation. Or in this case, defending accusations of violating R2R policy, and then lying. While there is a small group of people that seek and try to agitate such conflict, I believe most people want no part of. For me, unfortunately this type of participation is just not worth it.

Appreciate it! Looks like they pulled this stuff off the website.
O they didn’t I bought some and used it last night. Woke up this morning every snail was dead. Coral looked like crap. Tested for copper and 150gal system was at .25 copper. This sucks lots of time and lots of money down the drain. Not sure what to do now.

Thats awful!.. I did a 75% water change but by the time I realized the carbon killed everything it was too late anyway for my tank to pull through. I also ran a poly filter and seachems CU removal resin. Then my nitrate and phosphate bottomed out and have been dealing with Dinos... like my tank is fully cycling again.

Compelling result, but I don't understand how there's copper in aquarium carbon made form coconut shells. I'm sure @Randy Holmes-Farley will have greater insight, and I know @BeanAnimal is also knowledgeable about the process used to make aquarium carbon, maybe he'll have some idea what's going on.
hello we are currently investigating this issue if anyone have information results stories pictures please email myself [email protected] or bill [email protected] i can be text 239-214-4915 if one of ytour experts would please weigh in too like @Randy Holmes-Farley or @BeanAnimal it would be appreciated photos recipts batch numbers and stories im so sorry to all of you

This got me today. Stopped by Petco to pick up frozen food and grabbed this coconut carbon. I usually get the activated carbon but they were out. Put a bag in the sump this morning and came home to most of the LPS & zoas closed up and SPS looking terrible. Unbelievable.

I can't believe they still haven't pulled the product. Surely they've received a fair share of complaints by now, it's been going on for months.

To think that perhaps a quite technical, high end niche hobby that keeps animals with probably the most exacting needs of any captive wildlife group isn't best served by a retail dog food chain. Crazy.

I remember why I don't visit this site much anymore. Replies and attitudes like this. Have a nice day
