Does carbon bleach your corals ? (Kent carbon recall)

[Lampshade]

Wow, i tried new lights..... i tried new biopellets... i tried new powerheads.... I did 100+ gallons of water changes this month... and the whole time it was my damn carbon. Well, at least this way i had an excuse to buy a whole bunch of stuff for the tank. And now i can hopefully recover most of my SPS other than the 4-5 lost colonies.

The concern is that the batch of carbon contained unusually high levels of heavy metals which have an adverse effect on stony corals and clams in marine settings.

And all this time i though carbon sucked trace minerals out of my water....

Kent carbon in the garbage, any chance of me buying Kent ANYTHING again? NEVER!

I'm running out of brands to buy stuff from... so many ways to crash a reef tank and frustrate a reefer.
