This is an antibacterial agent, possessing both bacteriostatic and bactericidal properties. It is active against various gram-negative and gram-positive bacteria. It is indicated for the control of marine ulcer disease, and may be given orally (via gut-loaded shrimp) to treat systemic infections such as Vibrio.
Furazolidone can be administered as a bath to treat minor external skin infections, using a concentration of from 5 to 25 ppm (mg/L), depending on the severity of infection. Repeat the dosage every 24 hours with a partial water change before re-treatment, and continue the treatments for a minimum of 5 to 7 days (Furazolidone, 2004). An easy way to achieve the recommended dosage level is to add one level teaspoon for each 36 to 180 gallons (18.9 to 94.6 mg/gal). This medication will impair your biofilter, so use it in your hospital tank only.
