Does carbon bleach your corals ? (Kent carbon recall)

[christyf5]

I've got the same thing happening to a few SPS in my tank too. Bulbs are over a year old so I would have thought if it were the bulbs it would go the other way (browning out). I've been using the same 5gal pail of Kent carbon for at least a year though so I can't really say its the carbon attributing to it (unless I got overzealous and used too much). Odd that this is a coincidence though.

I always over use carbon. Always.

Maybe I have not had the same issues as I always use carbon and always have, so my water is always duper super clear.

I can see the increased clarity being a POSSIBLE culprit if you have never used carbon before.

But even when I switched to ROX, I never had a single issue. And ROX definitely made my water much, MUCH clearer than Kent ever did.

Before settling on carbon as the issue explore your heater/thermometer. Maybe that's an issue. Carbon is not the cause of bleaching in nature, so maybe try narrow down other factors.

As again, I highly doubt it's the carbon.

It's always easier to blame our equipment before ourselves.

Oh I totally agree. However like I said, I'm well into that 5gal bucket of Kent (and I've used Kent for about 7ish years now) and its not like I hit a "bad spot" or something to be just causing problems now. There are always a myriad of weird things going on with my tank and problems never get nailed down to any single thing. I'm not even sure why I posted to fuel the fire. Bored I guess.

isn't this the nature of the hobby in general? Detritus happens.
