- - SPS Bleached (http://www.canreef.com/vbulletin/showthread.php?t=84300)

Hey nano if it's any consolation I think we are in the same spot with our learning curve give or take a few points and I just bleached one of my first SPS too.

Like you I got a monti cap, and he's fine. Also have a birdnest, and he's doing okay too. The third guy (can't remember the name), wasn't in the tank for 3 hours and he went white on me. I think he died to warn me that I'm being too impatient. My tank's only a few months old after all, just like yours.

The beautiful pics up on this site that we see look so great but the owners are very quick to tell you that Rome wasn't built in a day and they've spent hundreds of dollars and hundreds of hours to make their set ups look so good. I bet there's not a single person on this forum that hasn't accidently killed a coral by inexperience or a simple mistake. Don't beat up yourself over it! And don't give your tank away either (unless it's to me :mrgreen:!)

NOPE... mine was definitly contaminated and it WAS NOT in the batch they recalled.

So anyone using Kent carbon recently bought should return it no matter what because it still might be contaminated despited them not issuing a recall!

Here is their reply when I asked them why my carbon was not in the recall:

"They could only test batches that they had samples for. That is why we are asking for samples from batches that we have not been able to test."

So they only did a recall in the carbon they tested, that's all. Anyone having some bad reaction with their corals after adding Kent carbon should remove it immediatly, then do a large water change and add some Polyfilter to filter out the copper and nickel which were the heavy metals contaminants in my batch of carbon.

If it is indeed one of the affected batches you should raise quite a stink with Big Al's because they should have received the recall letter weeks ago and should not have any of the affected carbon on their shelves.

NO NO and NO. They only recalled what they tested for! any batch of Kent carbon could be contaminated.

So do not garantee something like that!

I have a professional laboratory analysis of my carbon to prove this and my carbon was not in that list, yet it was very much contaminated.

What is that magnet going to do??? does copper attach to magnet????? I don't think so.

so it is a possibility that the carbon is the culprit, but not 100% closed case. at any rate it is out of the tank, I am doing water changes, and hope the corals turn around and open up in a day or 2. But still waiting to see if it solves anything, I also think adding carbon may have just added to it, so it could be a combination of 2 things

Wow, that is very interesting Daniella, thanks for sharing that.

Did you get a waterchange done Nano? How is everything looking?

yes 25% everything is still mad at me but I have some filter floss as well to hopefuly help out a bit

yes yes and yes......Ive seen a contaminated batch of kent carbon sticking to a magnet......I would like to see this professional laboratory analysis of your kent carbon......that must have cost a pretty penny to have your carbon tested like that....

Nano, the filter floss isn't likely to help. The Boyd Poly-Filter isn't typical filter floss...it is very good at absorbing heavy metals. It claims to do other things, but it is best known for its heavy metal absorbancy.

Here ya go Doug...

I got my water analyzed by a professional lab and the result show an abnormal concentration for copper especially.

The column named Daniella is my current aquarium water after 7 water changes and addition of polyfilter for a few days. The colum named "charbon" (carbon) is the result of analysing the water that come from a clean food grade container that had one gallon of water with 1/4 cup of well rinsed Kent Reef carbon running for 10 hours. I had put about one cup in my aquarium.

The result of 346 ug/l translate to .346 mg/l of copper, way too much and the reason why my corals died and bleached.

I guess this proof that more carbon than what they have in their recall list is affected since the expiration date on my container is EX21NO14, which is not in the list.

Magnaneese and kicket released is also a bit high with this carbon, but it is the copper that is to blame for the coral death. I am going to send a sample of the carbon and this lab result to Kent tomorrow.

So I did another 10g WC today, and have another 15g for later maybe tuesday. There are a few zoo's peeking out now which is nice to see. I think I might have 2 snails that survived. LPS still looks mad though. maybe later in the day or tomorrow will hold a different tale
