My purple had LL when I purchased it and the tank he was in had a Eco System set up for filteration. I feed Nori twice daily and it cleared up in a short period. I found that soaking the Nori in Kent Garlic every other day keeps everybody healthly.
So do you mean before you fed garlic the fish were unhealthy? Or if you stop feeding garlic the fish become unhealthy? IOW what has convinced you the garlic is doing anything at all??
