All I can seem to find locally, is Marineland activated carbon, think this would be good for now?? I want to get it it in as soon as possible, so can't order it, and wait a week. I'll get the ROX 0.8 on my next BRS order though.
Just an FYI on carbon.....

ROX is the purest along with thefilteguys(TFG), BRS Ligntie and TLF is next, Elos is also really good but they are NUTS what they want for it, ROX is cheaper.
CC (coconut carbon) GAC is very low in dust and hard compared to something like BD (Black Diamond), which makes BD a poorer choice of GAC over other GAC that have lower dust. The downside of CC GAC is that it is a poor choice for us, as the pores are way to small and almost all CC is very high in PO4. As one approaches the original material the Ash, contaminates and PO4 increase, except that which is acid washed. So, if we look at two bitum's, GAC like the TFG vs BD, the TFG is a much better choice in having less dust and contaminates. Then ask yourself the question " would any hospital use BD for dialysis" The answer would be a flat no way. BD has to much dust, is not acid washed, water rinsed or pH neural and has higher contaminants. TFG GAC is used in dialyzes, it is a medial grad GAC used for that very purpose. ROX, TFG, TLF and BRS Lignite area all acid washed. Acid washing, removes Ash and contaminates. BD is not acid washed. So, we are back to square one, choosing a lower grade Ca++ sup with more contaminates vs higher grade with less contaminates. Which one would Randy use? GAC is no different. We want a purer grade and at the same time these purer grades, that I listed above, are more adsorbent. As far as any potential dust goes, for ANY GAC, we can just use a post GAC micro filter. Then, how come is it that anybody that has used ROX or TFG will not go back to their old GAC choice. Reason, they almost could not believe the difference in water clarity and the price was worth it. If the theory holds water of, "just use more of it", then why don't companies that do water or liquid filtration just use "more of it". That way GAC companies could all just make one kind of GAC.
