Completely harmless to all aquatic organisms as well as aquatic plants, thus there is no danger of over use. Seachem Stability is the culmination of nearly a decade of research and development and represents the current state of the art in natural biological management.
Use 1 capful (5 mL) for each 40 L on the first day with a new aquarium. Then use 1 capful for each 80 L daily for 7 days. Fish and other aquatic species may be introduced at any time as long as dosage is maintained for 7 days. For optimum biofilter performance use 1 capful for each 40 L once a month or with each water change and whenever introducing new fish or whenever medicating an aquarium.
