Yeah, I think you are right that Candida is a fungus. In which case, Collodial silver probably wouldn't help since it is directed towards bacteria, I guess.
I didn't take pictures. Should have. Had three of the 'alien' type creatures and speculated for awhile that they were 'vegetable matter', specifically pieces of mostly broken down salad makings. But they really didn't look like that...more 'bug-like'. Come to think of it, the body wasn't the only colored part...the long thin filament legs had the slightest color too because I could barely see them in the water again the white background.
I could draw a picture and scan it in. Where to send?
