Seachem Stability 250 ml

Seachem Stability rapidly and safely establishes the biofilter in new marine or freshwater tanks, preventing New Tank Syndrome.

Description

Stability will rapidly and safely establish the aquarium biofilter in freshwater and marine systems, thereby preventing the #1 cause of fish death: "new tank syndrome". Stability is formulated specifically for the aquarium and contains a synergistic blend of aerobic, anaerobic, and facultative bacteria which facilitate the breakdown of waste organics, ammonia, nitrite, and nitrate. The bacteria employed by Stability are non-sulfur fixing and will not produce toxic hydrogen sulfide. Stability is completely harmless to all aquatic organisms as well as aquatic plants, thus there is no danger of over use. Stability is the culmination of nearly a decade of research and development and represents the current state of the art in natural biological management.

The bacteria used in competing products are inherently unstable. The conditions necessary for their growth and development fall into a very narrow range of temperatures, pH, organic loads, etc. When any of these parameters are not strictly within the proper range, the bacterial culture quickly crashes and dies. Stability does not contain any of the aforementioned bacteria.

Directions

Shake well before use. Turn off UV/ozone. Use 1 capful (5 mL) for each 40 L (10 US gallons) on the first day with a new aquarium. Then use 1 capful for each 80 L (20 US 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. For optimum biofilter performance use 1 capful for each 80 L (20 US gallons) once a month or with each water change and whenever introducing new fish or whenever medicating an aquarium. Product shelf life is 4 years from date of manufacture, see expiration date below.

Stability should ideally be used in conjunction with biological filtration such as Seachem Matrix. For emergency ammonia control, use Seachem AmGuard.

Part of managing nitrate and phosphate levels — see our guide to Nitrate & Phosphate for why these two parameters are tracked together.

Compatibility

Freshwater and marine, and safe in planted tanks and with invertebrates. The bacteria are non-sulphur species, so they cannot produce the hydrogen sulphide that some other starter cultures do.

Turn UV sterilisers and ozone off while you are dosing and for a day or two afterwards — both kill the bacteria you have just paid for. It can be used alongside Prime and the other Seachem conditioners.
