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.

Damn it, I even didn't have a small amount of that bad carbon :twised:
Thanks Daniella, I will reduce the lights for a few weeks. What is a polyfilter ? I have never heard of it before. Anyway, I'll call LFS and find out about it. I have more than 1/3 of completely white bleached corals in my tank. I still don't know what to do with them yet. Throw them away or wait to see if they come back ? Hmmmm ... good luck ? :twised: The rest of the corals are totally faded, only me the owner can recognize what were the original colors before, even my husband totally got lost has no clue. I am really &^%$# off with the Kent product. I will never buy anything that is made from this company again.

Ah Casey, stay in this hobby enough and you'll find you will get screwed often enough and by all the major brands, enough that you circle right back around to where you started :wink:

Hahaha ... I believe what you say. I was swearing that I would never touch any Coralife brands in my life again, then after a few years I bought a UV with that brand name again.
Thanks for the link.

Yeah after a few years it doesn't sting as much. Funny, I just put a polyfilter on my tank the other day hoping it would help. Also switched to the ROX 0.8 carbon from BRS. My water is shiny clean and hopefully the filter is doing its work. I didn't lose any corals so I'm thinking its not the carbon, my problems likely come from another source (of which I will never figure out but will likely be fixed in the midst of all the other "fixes" I do at the same time).

Do you still have the box of carbon and the invoice from the store you bought it?

They asked me for the bar code on the label and a proof of purchase and the address of the store where I bought it. They also asked for a sample of the carbon, but that did not seem to be a requirement though. Since I have plenty left I will send it.

Polyfilter is a filter media that change color as it absorb different contaminant. I will buy it today and put it in my tank.

I did another water change and now things are starting to look a bit better. My shaggy acropora is starting to return to normal.

However so far I lost all my beautiful blue sponges :( and all my beautiful and rare true pink digitatas. I have no idea whey they died and the other digitatas, orange and purple, did not die at all. Murphey's law dictate that the rarest and most beautiful are going to be those dying huh?

All my xenia have melted away...wierd...that was growing like weeds in my aquarium for 2 years and I kept pruning it and giving it away to friend and even throwing it in the garbage because I had too much of it. now I have none left. The little bit that was remaining finaly melted as well. very wierd.

The company is very nice though. I have good hope that if it is the carbon responsible, they will compensate people for their loss...i surely hope so.

I think if you have any coral left that is bleached but still have polyps and tissue, you should not throw them away. I once had an acropora bleach completely and even part if it died and it make a 100%, even 120% recovery in a month or two, so unless your coral have no more flesh and polyp, keep them and wait to see if they come back.

I had to throw away my monti cap with blue rim because it had no flesh any longer and algae was starting to cover it, a good sign that it was dead. Same with my pink digitata, it became all covered with brown stuff (not brown jelly though) sign that it was dead.

No, I didn't keep the container because I returned it and exchanged another brand. I still have the receipt though, the bar code must be somewhere in there.

if you returned it at the store, they probably returned it to the company. I would call the store and ask them what they did with it and if they still have it, ask for a sample of it to send to Kent.

In any case, you should contact Kent Marine and tell them your story.

Thanks Daniella, I will let my husband deal with them.
