Why It Works
Product Highlights
01
Rapidly Establishes Biofilter
Synergistic blend of aerobic, anaerobic, and facultative bacteria that break down ammonia, nitrite, nitrate, and waste organics to cycle new tanks faster.
02
Prevents New Tank Syndrome
New tank syndrome is the leading cause of fish death in new aquariums. Stability dramatically reduces the risk by rapidly seeding the biofilter before ammonia and nitrite can spike.
03
Safe for All Livestock & Plants
Completely harmless to all freshwater fish, shrimp, snails, and aquatic plants. No risk of overdose — safe to use with fish present from day one.

Common Questions
Seachem Stability FAQ
Is Stability safe for shrimp?
Yes — Seachem Stability is completely harmless to freshwater shrimp, snails, and all aquatic plants at any dose. There is no risk of overdose.
Do I need to turn off my UV sterilizer?
Yes — turn off UV sterilizers and ozone during the initial dosing period. UV light and ozone will kill the live bacteria before they can establish.
Should I use Stability with every water change?
For established tanks, adding Stability with each water change and whenever adding new fish helps reinforce the biofilter, especially if the water change is large or if the tank has been treated with medication.
What is the free shipping threshold?
Free shipping on plants and dry goods at $75+.
Can I add fish immediately after using Stability?
Yes — fish and other aquatic species may be introduced at any time during the initial 7-day dosing period as long as dosing is continued daily.
How long does it take to cycle a tank with Stability?
Stability significantly reduces cycle time but does not instantly cycle a tank. Most users see a functional cycle establish within 1–2 weeks with daily dosing, compared to 4–8 weeks without. Continue testing ammonia and nitrite until both read zero.
How is it shipped?
Packed securely and shipped Monday through Thursday via standard ground shipping. Plants and dry goods ship free at $75+. Transit times vary by location.
Can I order this with livestock?
Yes. Dry goods can ship together with livestock orders.
