About Bactershield®
Bactershield® is a revolutionary new way to help maintain fish optimum health. This bio-adhesive supplement repairs and strengthens the fish’s natural slime coat which protects against bacterial and fungal infections. Proven, natural oils and extracts are combined with a patented film forming matrix to help repair and strengthen a fish’s natural slime coat and help provide a protective shield around your fish. A fish’s slime coat acts as the first line of defense for fish against bacterial and fungal infections. Use Bactershield® as a preventative treatment after stressful events or for mild cases of common bacterial and fungal diseases such as fin and tail rot, popeye, body, mouth, or eye fungus, or gill disease. 
Active Ingredients: Chitosan, Cinnamon Oil, D-Limonene, Geranium Oil, Pine Oil, Rosemary Oil
