Seachem 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.100 gram size.

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 2-3 measures (included) per every every 40 L (10 US gallons). Repeat this dose every 72 hours for a maximum of 3 weeks.

Dosing in Food. 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.
