Erythromycin Fish Antibiotic Powder for Fin & Tail Rot – 1,000 Gallons is a concentrated erythromycin aquarium treatment intended primarily for label-listed gram-positive bacterial concerns in ornamental fish. This size provides label-directed coverage for up to 1,000 gallons when measured and applied according to the current product label.

Key Aquarium Treatment Features

• Also listed for selected aquarium concerns described as molly disease, tetra disease, wasting and swollen belly.
• The label includes guidance for cyanobacteria or red-slime concerns in aquarium systems.

Label-Listed Fish Health Concerns

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

• Fin rot
• Tail rot
• Mouth sores
• Eye sores
• Cloudy eyes
• Protruding eyes
• Popeye
• Molly disease
• Tetra disease
• Cyanobacteria
• Red slime
• Swollen belly
• Wasting disease
• 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 treatment.
2. Dose 1/4 teaspoon per 20 gallons of actual aquarium water.
3. Repeat after 24 hours and complete a partial water change between treatments.
4. Continue the extended bath for at least 5 days and no longer than 10 days, according to the label.
5. Stop and reassess if no improvement is visible within 5 days. Allow several days before introducing a different medication.

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.

Avoid combining erythromycin with other treatments unless the current labels permit it or a qualified aquatic professional specifically directs the combination.

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.
