Seachem Stability

Accelerated cycling of your aquarium with live bacteria

Seachem Stability is a highly concentrated blend of live nitrifying and denitrifying bacteria that cycles your aquarium safely and quickly. Unlike traditional bacteria products, Stability contains a complete mix of aerobic and anaerobic bacteria that break down ammonia, nitrite, and nitrate—for fully functional biological filtration in days instead of weeks.

Advantages

• Accelerated cycling: Build a complete biological filter in 7 days instead of 4-6 weeks
• Live Bacteria: Contains active, living bacterial strains that get to work immediately
• Complete nitrogen cycle: Breaks down ammonia, nitrite and nitrate for optimal water quality
• Safely Add Fish: Allows you to add fish during the run-in process
• Non-sulfate reducing: Does not produce toxic hydrogen sulfide like some other bacterial products
• Stable at room temperature: No refrigeration required, shelf life up to 4 years
• Works in fresh and salt water: Suitable for all aquarium types

When to use?

• For new aquariums: Essential for the safe start-up of a new aquarium
• After filter cleaning: Restores bacterial population after thorough filter maintenance
• After drug use: Repopulates the biological filter after antibiotic treatments
• In case of overstocking: Supports the biological filter in case of temporary overcrowding
• After water problems: Helps with recovery after ammonia or nitrite peaks
• When adding many new fish: Quickly increases filter capacity

How does it work?

Seachem Stability contains a synergistic blend of aerobic, anaerobic, and facultative bacteria. These bacteria colonize your filter media, substrate, and decorations, converting ammonia into nitrite, nitrite into nitrate, and finally breaking down nitrate into harmless nitrogen gas. This complete process ensures crystal-clear, safe water for your fish.

Usage

Running-in protocol (new aquariums):

• Day 1-7: Add 5 ml per 40 liters of aquarium water daily
• Use in combination with Seachem Prime for extra protection
• You can add some fish right away, but build up the population gradually
• Test ammonia and nitrite daily to monitor progress

Maintenance dosage: After the first week, you can add 5 ml per 40 litres weekly during water changes to support the bacterial population.

Emergencies: In case of ammonia peaks or after taking medication, you can double the dosage and add it daily until the values ​​are stable.

Tip: Shake the bottle well before use to evenly distribute the bacteria. Add Stability in an area with good water flow for optimal distribution.

Why Stability is Essential: Cycling an aquarium is the most dangerous phase for your fish. Stability drastically shortens this risky period and gives you the assurance that your biological filter is working quickly and effectively.
