TMP Sulfa is a mix of Trimethoprim and Sulfathiazole Sodium. This combination is great at reducing the buildup of resistance. Treats a variety of bacterial infections, both gram positive and gram negative by blocking two steps in the biosynthesis of nucleic acids and proteins essential to bacteria.

Treatment: 1/4 teaspoon (240 mg) per 10 gallons every 24 hours with a 25% water change before each treatment. Continue for 5-10 days.

*Works better than Triple Sulfa
