Key Aquarium Treatment Features

• Supports label-directed care for red body areas, streaking, peeling tissue, open ulcers and wasting.
• Commonly considered for myxobacterial concerns, fin and tail rot, open sores and Vibrio-related signs.
• The current label also includes a separate dip-treatment method for controlled short-duration exposure.

Label-Listed Fish Health Concerns

This product may be considered when the visible signs and the current label are consistent with concerns such as:

• Open ulcers
• Open sores
• Fin rot
• Tail rot
• Red body streaks
• Red areas
• Peeling skin
• White body
• Wasting disease
• Myxobacterial infection
• Vibrio anguillarum
• Bacterial infection
• Dermal fungus
• Shipping injury complications

Visible symptoms do not confirm a diagnosis. Similar signs may result from poor water quality, parasites, fungus, injury, toxins or environmental stress. Correct the aquarium environment and seek qualified aquatic guidance when the cause is uncertain.

Dosage and Application Directions

1. Condition the aquarium water and verify the actual treatment volume.
2. Use 1/4 teaspoon per 30 gallons of aquarium water.
3. A dose may be repeated after 24 hours after completing a 25–50% water change.
4. The label describes a treatment period of 5–10 days.
5. For dip treatment, follow the label exactly: 189–756 mg per 10 gallons for 1 hour, repeated daily for up to 10 days.

Label priority: Always compare these listing details with the instructions printed on the bottle you receive. The physical product label controls the amount, frequency, duration, compatibility and storage requirements.

Prepare the Treatment Aquarium

• Calculate dosage from the aquarium’s actual water volume, not its advertised capacity.
• Use a separate hospital or quarantine tank whenever practical.
• Test ammonia and nitrite before treatment and throughout the complete course.
• Remove activated carbon, UV or other equipment only when the current label directs you to do so.
• Maintain stable temperature and strong aeration while observing the fish closely.

Monitor ammonia and nitrite throughout use, treat in a hospital aquarium when possible and protect the powder from heat, moisture and bright light.

Coverage and Product Format

The concentrated powder format is designed for accurate measuring in a controlled treatment system. This package treats up to 1,000 gallons at the label-directed rate, making the coverage easy to compare with your hospital tank, quarantine aquarium or ornamental pond treatment volume.
