? About Activated Carbon

[butts182]

Can too much activated carbon cause recession in chalices and other corals? I added some fresh Marineland premium activated carbon a few days ago and now a few of my chalices are receeding. Tank params are pretty stable (ALK = 8, Ca = 450, Phos = 0, Nitrate = 10), but I just don't know if this could be related. I add the carbon to a filter bag, rinse it with water, and then put in in the sump. Does anyone have any input?

I have read about it but never experienced it myself... I know unrinsed can cause problems with fish such as hlle...

The carbon is stripping the water of the nutrients that the chalices are used to absorbing. I would try target feeding to see id it reverses or remove the carbon

personal experience...i ran a crap load of carbon for awhile. I thought it would be good for my sps to have super clean water...was I wrong. All my corals mostly sps started losing color and than they started withering a way. All my tangs fins started rotting a way as well..most likely HLLE. I yanked the carbon completely out of the tank about a month ago and everything is slowly starting color up again.
