Fritz Mardel 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 bacteria and fungi . 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 such as fin and tail rot, popeye, body, mouth, or eye fungus, or gill disease.
