2. Follow Label Dosing: Use correct mg-per-gallon guidance and duration; avoid early discontinuation.
3. Protect Water Quality: Remove carbon during dosing if instructed; monitor ammonia/nitrite; perform partial water changes as directed.
4. Quarantine: Treat sick fish in a hospital tank to protect beneficial bacteria in the display tank.
5. Post-Treatment: Restore filtration media as directed and consider probiotic/bacterial supplements.
