Garlic, serious discussion

[Aquattro]

First time I used garlic was when my brown tang got ich. He was covered in dots. I soaked nori in fresh squeezed garlic an fed normally. Both tangs went at it like it was there last meal. Ich fully vanished in 24 hours. I stopped feeding garlic. Ich came back. Added garlic, ich went away less than 24 hours. I continued to feed garlic for 10 days further, never saw ich again to this day.
I can't prove garlic does anything, but my fish think it works, and that's good enough for me.
