Seachem Stability 500mL ^123

Rapid and Safe Aquarium Biofilter Booster for Freshwater and Marine Systems

Seachem Stability® is a state-of-the-art biological supplement designed to rapidly and safely establish the aquarium biofilter, helping prevent the #1 cause of fish death: “new tank syndrome.” Ideal for both freshwater and marine systems, Stability® contains a synergistic blend of aerobic, anaerobic, and facultative bacteria that efficiently break down waste organics, ammonia, nitrite, and nitrate.

The bacteria in Stability® are robust and adaptable, thriving across a wide range of temperatures, pH levels, and organic loads. They are non-sulfur fixing, completely harmless to fish, invertebrates, and plants, and can even become more effective under high organic load conditions. Stability® uses spore-form bacteria that activate upon addition to the aquarium, requiring no refrigeration.

Key Benefits:

• Rapidly establishes a healthy aquarium biofilter

• Breaks down ammonia, nitrite, nitrate, and organic waste

• Safe for all fish, invertebrates, and aquatic plants

• Non-sulfur fixing; prevents hydrogen sulfide formation

• Highly adaptable bacteria for varied tank conditions

• Supports emergency situations, increased bioload, and water changes

• Spore-form bacteria that activate in the aquarium; no refrigeration required

Usage Guidelines:

• Dose daily for 7 days when cycling a new tank, or as recommended

• Can boost bacteria during water changes or after adding new fish

• Turn off UV and ozone filters during dosing (7 days for cycling, 24 hours for additions)

• Can be combined with Seachem AmGuard if ammonia is present for rapid detoxification

FAQ Highlights:

• Overdosing Stability® is safe; rare bacterial blooms self-clear

• Most tanks cycle fully within 4–6 weeks using Stability®

• For fishless cycling, add a small ammonia source or pinch of food until ammonia is detected
