Dosage Guidelines & Instructions

Directions for Use:

Set Up a Separate Treatment Area

Whenever possible, move affected fish to a dedicated hospital or quarantine tank before dosing. A separate treatment area allows for easier observation, better control of water quality, and more convenient repeat dosing.

Dose for Aquariums, Ponds, and Hospital Tanks

Use one tablet (500 mg) per 20 gallons of water. Dissolve the tablet in a small amount of water first, then add it directly into the aquarium, pond, or hospital tank.

Repeat Every 24 Hours

Repeat the dose every 24 hours for 5 to 7 days. Do not exceed 7 days of continuous treatment unless otherwise directed by a qualified aquatic professional.

Perform Daily Water Changes

It is recommended that a 1/4 water change be made daily during treatment. Stable water conditions are an important part of aquarium care during any treatment period.

Monitor the System Closely

During treatment, observe fish behavior, aeration, and overall water conditions closely. Hospital tank use is often preferred for controlled dosing and daily monitoring.

Pro Tip: Treating fish in a separate hospital tank whenever possible can help reduce stress on the main display aquarium and make dosing, observation, and water changes easier to manage.
