I know it is candida for many reasons - long history of Antibiotics , etc. My friend has a trache and because of suctioning I look right at it. When the candida was healthy it floated with big thick spore laden cload underneath - I think it has been at a stage of putting out mucous to cover itself from the O3, but it is getting weaker and weaker - now there is little floating and the slime is on the bottom of the suction pot. Much less mucous too.
