Correct identification of a fish health problem is essential. Similar symptoms may result from water-quality stress, parasites, bacterial disease, injury, or environmental conditions.

2. Use 1/4 teaspoon per 20 gallons of water.
3. Repeat every 24 hours with a 25% water change before each treatment.
4. Treat for 5–7 days. The source label advises using half the normal dose for especially sensitive fish such as tetras and neons.

Important Treatment Guidance

Use a separate hospital tank whenever possible to protect biological filtration and simplify observation during treatment.

• Test water quality before and during treatment, including ammonia and nitrite.
• Use a dedicated hospital or quarantine tank whenever practical.
• Remove or pause chemical filtration and other equipment only when the product directions require it.
• Observe fish closely and discontinue use if unexpected stress or adverse reactions occur.
• Store tightly closed, away from children, moisture, heat, and bright light.
