About this item

  • 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 safe 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.

From the manufacturer

Seachem Prime Fresh and Saltwater Conditioner

Prime is the complete and concentrated conditioner for both fresh and saltwater. Prime removes chlorine, chloramine and detoxifies ammonia, nitrite, and nitrate. It is non-acidic and will not impact pH.

Prime may be used during tank cycling to alleviate ammonia/nitrite toxicity. It contains a binder which renders ammonia, nitrite, and nitrate non-toxic, allowing the biofilter to more efficiently remove them. It will also detoxify any heavy metals found in the tap water at typical concentration levels. Use at start-up and whenever adding or replacing water. When transporting or quarantining fish, use Seachem StressGuard. When adding new fish, use Stability. Both are ideal for use with Prime.

Product description

Size:1 L

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

For over three decades, Seachem has been a company rooted in sound science. Our experience in the hobby and an educated staff of chemists and biologists are part of the package when you purchase Seachem products. Seachem remains as one of the few surviving independent and privately owned pet care companies. Seachem is owned and operated by hobbyists. All of our employees are hobbyists who maintain aquariums at home and at the office. Seachem itself was started because one such passionate hobbyist - Dr. Leo G. Morin (Founder) - recognized that the available solutions to aquarists problem wanting. This resulted in Seachem’s very first product: Cupraplex (today known as Cupramine). Over thirty years later Seachem is still approaching old problems in a new way.

Seachem’s philosophy is that the knowledgeable hobbyist makes the best customer. This is reflected in solid and reliable customer education and support as well as products proven in science and performance. While Seachem has grown rapidly into a national and international firm, it retains the culture of a small company and is readily available to its customers.

Important information

Directions

Use 1 capful (5 mL) for each 200 L (50 US gallons) of new water. For smaller volumes, please note each cap thread is approximately 1 mL. May be added to aquarium directly, but better if added to new water first. If adding directly to aquarium, base dose on aquarium volume. Sulfur odor is normal. For exceptionally high chloramine concentrations, a double dose may be used safely. To detoxify nitrite in an emergency, up to 5 times normal dose may be used. If temperature is > 30 °C (86 °F) and chlorine or ammonia levels are low, use a half dose.
