    I'm talking leeching though, not exhausted :D Let me get some help from RHF, Boomer and Bob (ESV). All three are well versed in this area.

    You can have a bag of carbon filled to 1% capacity, put it in clean water, and leach out. It isn't exhausted :p

    If you have nothing else to soak up junk yet you are adding more junk into the tank, the levels of junk increases and you have this "OMG, my carbon is leaching!" when really you have "OMG, the trash cans are full but I am keep trying to put more and more trash in them"

    Much better example of what I was trying to say! ;)

    Now wait, did I say MASSIVE influx? You can debate what I say, but you can't put words in my mouth AND debate me :D[/quote]

    Nope, you didn't :D

    My point is that if it's just an equilibrium situation with good quality water, you're not gonna get massive outflux of adsorbed junk, so it's not a big deal.

    And the only way to leach large quantities would be to have the carbon equilibrate in cruddy water, then get it into decent water.

    That could happen if someone doesn't keep up with water and carbon changes, then does a big water change without changing carbon.

    Even then, the concentration of DOC shouldn't be any worse than before the water change.

    Hey Justin, you're a chem geek too? I can't remember :D

    You bring the organic compounds. I'll bring the Mettler balance :D

    ;D I wish I could say I was, unfortunately my intelligence does not peak in that plane of consciousness ;)
    I think my geekery naturally gravitates towards other geeks allowing me to inconspicuously blend in though :D

    Boomer helped me confidently chose the carbon I chose for the GB I did a year or two ago though. Good guy and great resource, the knowledge is DEEP in that forum! Still have a gallon of it left!! :eek:

    Where do you get yours Gresh?

    cant remember the exact link, I could find it but mine was something along the lines of activatedcarboncorp.com I think(again may be bad link but something along those lines, down in So.Cal)

    Yah, Chem Forum is good. High s/n ratio :D

    Sorry norm, I don't really do anything organic. You bring the balance, and I'll bring the lasers.

    I picked up the ROX 0.8 from bulk reef. I think the 0.8 refers to the pellet cylinder diameter being 0.8mm.

    mines lab grade ;)

    I asked Boomer, Randy and a bunch of other well qualified people to weigh in on this in a private forum. Thus far one of them reminded me carbon not only can leech stuff out, it breaks down as well.

    "Lab grade" is relative :p This coming from someone who has been in a research lab for the past 7 years..

    However, toss at me impurity #'s and BET surface area and then I may start salivating.

    damn you..made me spend time looking into my carbon. It looks like Rox 0.8 is also "lab grade"

    Dunno the data. A person with a PHD in water Chem actually made the puechase :D

    I don't trust PhD's. They are full of themselves.

    You're comment on not trusting PHD's came from reading a post where I said I dunno, I didn't make the purchase :D
