Does carbon bleach your corals ? (Kent carbon recall)

jjntm · #1 02-19-2012, 05:52 PM

My buddy rob (canuckgod420) mentioned this same issue on here a couple of months back after switching to kent carbon, EXACTLY the same thing happened!!!! he was on here looking for advice and NOBODY offered any....lol... now everyone chimes in....

Good news for you guys/ladies is that it will all come back around. We believe it is just that the carbon stripped the water too clean and allowed excessive light penetration which bleached the corals (like switching from t5 to MH or swapping to led and keeping the intensity to high from the get go.) It took weeks of frustration and heartache before his tank showed signs of coming back around. I believe he completely cut out the carbon... and his tank colors are AMAZING!!! now... growth is better then ever and his tank is once again top 3 I ever EVER seen!!!!!

I thought someone had mentioned possible issues with Kent carbon awhile ago, but I was searching the forums and couldn't find it, so I figured I was imagining it. Now I'm going to go look again now I know who it was...

EDIT: Here is canuckgod420's experiences back in November... http://www.canreef.com/vbulletin/showthread.php?t=80526

wow... reef central thread store owner lost a ton of coral.... I really hope kent steps up to the plate and pays for or replaces everyones losses... everyone affected should write a mass email to them stating their displeasure! The more ppl that send to them what happened the better it is for them to investigate what went wrong...

Thats funny Myka, you even posted a response to my thread.

Anyway, its all good now, everything looks great and growing fast.

I'm actually thinking of adding this carbon every few months to shock up the corals a bit and watch them explode in growth and colour again.

Having a bunch of disgruntled reef keepers suing for compensation is a good way to put a company out of business. I'm not sure I agree with that...take a look at what happened to PFO. I'm sure there are more people that miss PFO then there are that are mad.

Store owners should know better than to put $20K of coral in one system - that's a really bad idea. That's called laziness...it is easier to maintain one or two big systems than several smaller ones. You can't purchase much in the way of insurance on live corals or fish, so they have to create their own types of insurance. Multiple systems is the best insurance they can get. I still feel darn awful for the store owner who lost this huge investment, as well as the animals that died though. That is awful.

Yeah, I was really thinking I was losing it. I spent at least 20 minutes hunting for that thread before deciding I had lost my mind. Then jjntm mentioned your name and I found the thread in approximately 8 seconds!

A lot of stores have common water in their system. I am not sure if you realize this but he lost 10k of coral worth...and it does not take that much in coral to reach that amount. I personaly have about 3k to 4k in corals worth. I lost about half so far.

I can think of plenty of coral stores here that would have the same exact issue because all their aquariums are connected with the same water. It is very common.

I don't think they do it out of laziness, probably more out of economical issue. It is less expensive to have a big central system I guess.

And your point may not be valid even if he had a few independant systems. Assuming he was doing the regular maintenance shedule of replacing carbon, what is to say that he would not have put new fresh carbon in all of his independant tanks killing everyting anyway?

I got a reply from Kent Marine. They requested that I send a sample of the carbon (understandable) and the bar code on the product, plus they want to see pics of the corals that have died and what ever receipt I have.

Of course I don't have receipt for most of my corals because some where bought like 2 years ago or at least more than one year. Some were bought as group buy and I was not the one with the invoice, and finally some were bought from other reefers and I don't have receipts for those. But I think that from the pics they can make out what is the value of the coral anyway.

They seem nice and offered me good advices on how to bring my system back to normal, lower the light for a few weeks until the corals recover, use polyfilter to remove what ever contaminant is in the water, feed corals with vitamine and food and replenish trace element that the polyfilter will remove. Seem like a good plan.

I will be sending them the sample of the carbon and the documents this week.

They said that polyfilter will remove heavy metal and contaminants if that is the problem so I am going to buy this stuff tomorrow and do another water change.

As soon as I find out what is the problem, I will post here.

Question here..if it is copper or other heavy metal, will polyfilter remove it from my liverock as well or will I have to replace my liverock?

polyfilter will remove it from the water as it leaches from your rock, however if your rock keeps leaching without the polyfilter, you'll always have it in your water. I guess it also depends on what kind of levels were in the water in the first place and whether it was taken up by the rock. The polyfilter might let you know what is in the water also, as it changes color depending on what it is removing.
