Carbon FW or SW??

[AJ_77]

As I mentioned to Brad, I wish I could remember what brand it was, and whether or not there were white bits in it or not... I seem to think that I would avoid any white chips in the carbon, having read that a "good" grade was needed.

It was, I believe, a 3-pack of pouches for either the Fluval or Aquaclear. I'll keep looking, but I don't expect to be at the LFS tonight.

I see on that site that Fluval has their zeo-carb product, and maybe I was that dense and used it... Whatever I used, it sure seemed to spike the phosphates, and that was the only clear variable at the time.
