  • Treats many bacterial, fungal, and protozoan infestations
  • Broad spectrum antibiotic and anti-fungal medication
  • Most effective of the sulfa drugs in saltwater
  • Absorbed through gills

SulfaPlex™ is an effective and safe treatment for many bacterial, fungal and protozoan infestations in the aquarium. While it can be used in both freshwater and saltwater, it is particularly effective against the common bacterial and fungal infections of freshwater fish. It is also among the gentler antibiotics, and great for treating fish that are already stressed. It is easily removed with carbon and does not impair nitrification.

Active ingredients: sulfathiazole (69%) Inactive ingredients: excipients (31%)

SulfaPlex™ is appropriate for treating a variety of bacterial, fungal and protozoan infestations. Below are some of the more common diseases treatable with SulfaPlex™. Be aware that many diseases and infections share similar physical and behavioral symptoms, e.g. clamped fins, lesions, loss of appetite.

 

Seachem Use in BFA Item #
Sulfaplex 5 gm (.18 oz) Saltwater & Freshwater SC08420

 

Remove all invertebrates - these are extremely sensitive to medication. Turn off UV filters, ozone filters, and remove chemical filtration like MatrixCarbon and Purigen®. Use 2-3 measures (included) per every every 40 L (10 US gallons). Repeat this dose every 72 hours for a maximum of 3 weeks.

SulfaPlex™ is most effective when used in the water, but it can also be added to the food. Feed the medicated food mix (recipe below) every day until the infection clears or up to 3 weeks.

  • 1 scoop SulfaPlex™
  • 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™ or Entice™.

After Treating

When the treatment period is over, SulfaPlex™ can easily be removed using activated filter carbon like MatrixCarbon™. It does not linger in the substrate or filter media of the tank.
