I think the article mentioned that the fine carbon dust may be the cause..this is still open... so if you use good quality carbon ( like rowa) and you had washed away the fine dust of carbon...you may not see HLLE ....I think on the safe side, use only when neccessary.. personally I've seen it in freshwater ( discus) and saltwater ( emperor angel) when I used carbon ... but when removed... they healed up and I've stop using carbon since...unless need to remove copper etc..
