About this item

Product details

Seachem Stability quickly stabilizes new aquarium environments and establishes the bio-filter for rapid, safe startup. Its unique blend of aerobic, anaerobic, and facultative bacteria break down organic waste and toxic ammonia, nitrate, and nitrite to prevent "new tank syndrome" the first cause of fish death. Unlike competing products, the bacteria employed by Stability are non-sulfur fixing and will not produce toxic hydrogen sulfide. Stability is completely harmless to all aquatic organisms (including aquatic plants) so there is no danger of overuse. The result of nearly a decade of research and development, Seachem Stability represents the current state of the art in natural biological management. Directions: Use 1 capful (5 ml) for each 40 L (10 gallons) on the first day with a new aquarium. After that use 1 capful for each 80 L (20 gallons) daily for 7 days. Fish and other aquatic species may be introduced at any time as long as dosage is maintained for 7 days.
