Ooops, my bad. I should've read Tim's post in detail. OK, so what does this chloride salt do to phosphates? Does it bind to them and precipitate them? Is that a long-term solution? Does that happen to both organic and inorganic phosphates? Is there a possibility that at a future date, under the right coditions these phosphates reverse to their previous condition and pollute the tank? I guess I like the idea that with GFO you throw away the phosphates when you change out the media.

I apologie if this was discussed before. Chemistry was never my thing.
