Differences between Premium Activated Carbon?

[sanfordbhines]

I have been getting this for the last year. Seems to work pretty good.

Is something like this similar to the carbon up above?

Have any of you tried the "ebay" carbon before? Is it any better than the stuff from Drsfosters? Any other opinions on this?


Thanks.

The bulk reef supply ROX is probably better than the black diamond you've been using. I think you can get it cheaper directly from them...bulkreefsupply.com
