Key Aquarium Treatment Features

• Relevant to listed concerns associated with Aeromonas, Pseudomonas and myxobacterial organisms.
• Can be administered through aquarium water or incorporated into feed according to the current label.

Label-Listed Fish Health Concerns

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

• Raised scales
• Swollen belly
• Swim bladder inflammation
• Bloody fins
• Bloody scales
• Gill disease
• Marine ulcer disease
• Hemorrhagic septicemia
• Aeromonas
• Pseudomonas
• Myxobacterial infection
• Bacterial infection

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 before measuring the powder.
2. Use 1/4 teaspoon per 20 gallons every 24 hours.
3. Complete a 25% water change before each repeat treatment.
4. For label-directed feed use, mix 2 teaspoons or 1.2 grams per pound of food for 14–21 days.
5. Calcium and magnesium can bind oxytetracycline. Consider water hardness and pH; when pH is 8.0 or higher or water is hard, the label suggests administration in food.

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.

Use a hospital aquarium whenever possible and monitor ammonia, nitrite, pH and hardness throughout the treatment period.

Coverage and Product Format

The concentrated powder format is designed for accurate measuring in a controlled treatment system. This package treats up to 200 gallons at the label-directed rate, making the coverage easy to compare with your hospital tank, quarantine aquarium or ornamental pond treatment volume.
