    • Broad spectrum antibiotic effective against most external infections
    • Safe for marine and freshwater
    • Minimal impact on bio-filter

          Overview

          NeoPlex™ is a broad spectrum antibiotic effective against most external infections of both marine and freshwater fish. Used as directed, NeoPlex™ will not discolor the water or damage the filter bed. It is well tolerated by invertebrates, although delicate species may be stressed.

          Active ingredients: neomycin sulfate (43%) Inactive ingredients: excipients (57%)

          Indications

          NeoPlex™ is appropriate for treating a variety of external infections of both marine and freshwater fish. Below are some of the more common diseases treatable with NeoPlex™. Be aware that many diseases and infections share similar physical and behavioral symptoms, e.g. clamped fins, lesions, loss of appetite.

          Directions

          Dosing in Water

          Remove all invertebrates - these are extremely sensitive to medication. Turn off UV filters, ozone filters, and remove chemical filtration like MatrixCarbon™and Purigen®. Use 1 measure (included) per every 8 L (2 US gallons). Repeat this dose every 7 days to a maximum of 3 weeks. This will treat external bacterial infections.

          Dosing in Food

          Feed the medicated food mix every day until the infection clears or up to 1 week. This will treat internal bacterial infections. This medicated food can be refrigerated or frozen between feedings.

          • 1 scoop NeoPlex™
          • 1 scoop Focus™
          • 1 tbsp food (preferably pellets or frozen food)
          • A few drops of water if using a dry food

          To enhance palatability use with GarlicGuard™.

          After Treating

          When the treatment period is over, NeoPlex™ can easily be removed using activated filter carbon like MatrixCarbon™. It does not linger in the substrate or filter media of the tank. Remove with carbon before turning on UV.

          Pros and cons
