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%).

Compatibility

Freshwater and marine, though it is most effective against the bacterial and fungal infections common in fresh water.

Not compatible with invertebrates — remove them before treating. Take chemical filtration out and switch UV and ozone off while dosing.
