POWERFUL TREATMENT: Seachem Prime is a complete and concentrated conditioner for both freshwater and saltwater fish tanks, working hard to remove chlorine and chloramine.

REMOVER: Seachem Prime immediately and permanently removes chlorine and chloramine, successfully allowing the bio filter to remove ammonia, nitrite, and nitrate while they are detoxified for 48 hours.

DETOXIFIER: Seachem Prime effectively detoxifies ammonia, nitrite, and heavy metals found in the tap water at typical concentration levels, providing a ideal environment for your betta, tetra, or other fish.

USE: Use 1 capful (5 mL) of Seachem Prime for each 200 L (50 US gallons) of new or replacement water. For best results, add Seachem Prime to new water first. For exceptionally high chloramine concentrations, a double dose may be used safely. For smaller volumes, use 2 drops per gallon.

SAFETY: In case of an emergency, the 5x dose of Seachem Prime may be used for both ammonia and nitrite. Use a ½ dose if the water temperature is > 30°C (86°F) and chlorine or ammonia levels are low.

Features

TANK STABILIZATION: Seachem 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".

TREATMENT: 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.

BACTERIA GROWTH: The necessary conditions for the growth of Stability's bacteria strains encompass a very broad range. When other bacteria begin to die off (usually from high organic loads caused by the unknown death of an organism), Stability simply becomes more effective.

USE: Shake Seachem Stability well before use and turn off UV/ozone filter. 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.

SAFE: 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 overuse.

BINDER: Seachem Zeolite is a naturally occurring, highly-porous mineral that binds ammonia and heavy metals through an ion exchange mechanism.

REMOVER: Seachem Zeolite works in marine and freshwater to remove harmful metal ions such as lead, copper, nickel, and zinc without depleting calcium in saltwater nor increase general hardness in freshwater where the ionic strength is low.

DIRECTIONS: Use 250 mL (1 cup) of Seachem Zeolite for every 200 L (50 US gallons). For smaller aquariums, the equivalent dose is 5 mL (1 level teaspoon) per 4 L (1 US gallon). This amount of Seachem Zeolite will remove up to 0.5 mg/L ammonia. Ammonia levels should then drop to zero within 24-48 hours. At this point, the zeolite can be removed or replaced with Active Carbon.

FOR BEST RESULTS: Seachem Zeolite should be rinsed before use and placed so as to maximize the flow of water through it, but not so that it tumbles against itself in flow. Zeolite may be used in a canister filter, media chamber, box filter, or any high flow area of a trickle filter. Use of a filter bag is also recommended.

SAFETY: Be sure to wash thoroughly after handling Seachem Zeolite and store this product in its original container in a cool, dry area away from food or incompatible materials.
