Seachem Stability (100 mL) – Aquarium Bio-Filter Booster

Description: Seachem Stability is a powerful new-tank stabilization formula that quickly establishes your aquarium's biological filtration by introducing a balanced blend of aerobic, anaerobic, and facultative bacteria. Safe for freshwater or marine setups, Stability prevents “new tank syndrome” and helps break down waste, ammonia, nitrite, and nitrate—without releasing toxic hydrogen sulfide 

Usage Instructions:

• Initial dose (new tank): 1 capful (approx. 5 mL) for each 40 L (10 gal) on the first day.
• Daily dose (7 days): 1 capful per 80 L (20 gal) per day. Meat of the cycle.
• Maintenance: Use 1 capful per 80 L (20 gal) monthly, with water changes, or when adding new fish or medicating
• Note: Turn off UV or ozone for at least 7 days (or 24 hours for occasional dosing), as these can kill the beneficial bacteria 

Why It Matters:
Stability’s strains are stable and resilient across a broad range of conditions—when other bacteria falter, Stability thrives—making it unmatched in maintaining a healthy, cycling tank
