I remember reading about someone posting feeding AB+ soaked food to their Biota yellow tang(it was you Duude). So when I finally got one last month I started doing so right away to avoid fish getting HLLE. Thanks for the idea, my Biota YT is doing great with no signs of HLLE.I have been soaking my frozen foods in the AB+ twice a week. Corals and fish get the benefits that way. I swear I read someplace that AB+ can be used as a food soak to help HLLE.
