Does carbon bleach your corals ? (Kent carbon recall)

[daniella3d]

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.

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 ? 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.
