I just tried the magnet test on unused Korallen or zeo carbon and elite aquatic premium carbon and they both were picked up by the magnet. Not sure why but my question now is, How accurate is this procedure. Can everyone with a strong magnet test their carbon please. So far Black diamond,HBH,Korallen,Elite Aquatic premium. all are magnetic
