Does carbon bleach your corals ? (Kent carbon recall)

[Casey8]

I am glad you had chimed in that you had the same problem with this Kent carbon too. If not, I may have thought I am the only one complaining about bleaching corals for using bad carbon. Nothing I can do about coral's bleaching now, I just hope whatever I have left are recovering soon.

I once had a shaggy acropora bleach completely and no polyp extension after I took it from one tank to the other without any acclimatation. I did not care about it because under T5 it was all brown and really ugly. It remained for about a month like that and after a month the polyps started to come out and that coral is gorgious today. It has grown about 10 times the size. It took about 2 months to color up to a very nice bleu/green with purple tips under metal halide.

So there is hope

I will return that carbon to the store for a refound and tell them what hapened and that I am not the only one and will take the Seachem carbon instead.
