Does carbon bleach your corals ? (Kent carbon recall)

The OP used this carbon for years without problem before this hapened. I have been using other brand of carbon without problem (seachem), in fact, I never had any problem with my corals or reef since the beginning 2 years ago.

Too much light? No I doubt it in my case since it hapened during the night and there was no change of ligth previously either. My 250 watt Phoenix 14 has been there for 4 months and corals were thriving, acropora growing 1" per month previous to the addition of carbon.

it's definitly something else.

I agree. But I just don't see carbon being the issue.

During the night... Maybe corals fighting. Killing parts off. Dead corals lose color too.

Also, too much light is a suggestion. I would still lean to heat spikes.

I had to remove an unfaithful finnex.


Has anyone done extensive research on natures bleaching? Perhaps there are some similar factors we duplicate in tanks. Like pollution.

Can anyone educate us better?

I'm no expert on this issue, just trying to help.
