xWhy choose Seachem Prime for your aquarium?
Seachem Prime is a complete, concentrated water conditioner designed for both freshwater and saltwater tanks. It targets common tap-water challenges—chlorine and chloramine—and works to support your tank’s biological filtration. Rooted in decades of hobbyist science, Prime blends practical dosing with the reliability you expect from a company led by experienced aquarists and scientists.
What does Prime do?
- Powerful treatment: a complete conditioner for fresh and saltwater setups that targets chlorine and chloramine upfront.
- Detoxifying action: neutralizes chlorine and chloramine immediately and permanently, giving your biofilter time to address ammonia, nitrite, and nitrate while they’re detoxified for 48 hours.
- Detoxifier role: reduces the impact of ammonia, nitrite, and trace metals at typical tap-water levels, helping create a friendlier environment for your fish.
How to use Prime
- For new or replacement water, add 1 capful (5 mL) per 200 L (50 US gallons). Best practice: add Prime to the new water first.
- For exceptionally high chloramine concentrations, a double dose may be used safely.
- For smaller volumes, use 2 drops per gallon.
- Safety note: in emergencies, a 5x dose can be used for both ammonia and nitrite. If water temperature is over 30°C (86°F) and chlorine or ammonia levels are low, consider a ½ dose.
Real-world benefits and use cases
When you’re preparing a new tank or performing routine water changes, Prime helps you manage chlorine, chloramine, and trace metals so your fish experience less immediate stress. The detoxification window offers your beneficial bacteria time to respond as you acclimate livestock, and the dosing options give you flexibility based on tank size and water quality.
Common scenarios include setting up a freshwater community tank, preparing a betta or tetra environment, or maintaining a saltwater system where trace metals can be a consideration. Prime’s combination of immediate removal and a 48-hour detoxification window makes it a versatile step in many routine tasks, from weekly changes to new-tank cycling.
