    HLLE and Activated Carbon

    Below is a link to a very interesting article in Coral, The Reef & Marine Aquarium Magazine, published yesterday in which Jay F. Hemdal connects some dots between use of activated lignite carbon in marine aquariums and adverse affects to certain fish species susceptible to Head and Lateal Line Erosion (HLLE). Great stuff.

    Hat tip to the G man for the highlight.

    Actually I think you beat me! Mine has a summary though which looks better on the homepage! ;)
    (when you get something good keep that in mind when posting then send me a pm to highlight)

    It has been suspected for a long time that carbon can be involved in HLLE, but should be taken with a grain of salt. Certainly there should be caution taken when using carbon. Don't use too much, use high quality, rinse well etc... However, I've used carbon for the better part of a decade and strongly believe that the benefits outweigh the risks.

    While, carbon may be correlated with HLLE, they have not shown it to be the cause or shown a definitive mechanism for how it is involved. There are likely unknown interactions with other factors. In fact I think it is safe to say that activated carbon alone does not "cause" HLLE. I've never seen HLLE in my tanks in that time, running activated carbon essentially 100% of the time. And most people who run carbon also have not seen HLLE.

    Also, the findings were limited to lignite coal-based) carbon so, other carbons are possibly safer. Although, I've mostly used lignite and have never seen HLLE, so, I'm not particularly worried. Carbon IME provides great benefit, I would be more worried about trying to run a reef without it, but certainly if you notice HLLE, you may want to cut back or remove altogether. If you are worried, there are many products which are not lignite based, which may be preferable.

    wow...don't buy cheap carbon is the general conclusion i come to from that. i really didn't expect results that were THAT obvious. here isa bump for BRS and thier premium ROX .8 carbon.
