Seachem Prime®: The Ultimate Water Conditioner for Your Aquarium

Seachem Prime® is a complete and concentrated water conditioner designed for both freshwater and saltwater aquariums. Known for its unmatched quality, concentration, and effectiveness, Prime® removes harmful substances like chlorine and chloramine while detoxifying ammonia, nitrite, and nitrate. It is non-acidic, does not affect pH levels, and is safe for reef systems as it will not over-activate protein skimmers.   

Key Features:

• Chlorine & Chloramine Removal: Instantly neutralizes harmful chlorine and chloramine.   
• Detoxifies Ammonia, Nitrite, & Nitrate: Makes these compounds non-toxic, allowing the biofilter to process them efficiently.   
• Highly Concentrated: Up to 5x more concentrated than competing products, offering exceptional value.   
• Non-Acidic Formula: Will not alter aquarium pH.   
• Reef-Safe: Does not interfere with protein skimmers, making it ideal for reef hobbyists.   
• Heavy Metal Detoxification: Safely binds heavy metals typically found in tap water.   
• Safe for Cycling Tanks: Alleviates ammonia and nitrite toxicity during the cycling process.   

Recommended Companion Products:

• Use StressGuard™ for stress reduction during fish transport or quarantine.   
• Use Stability® to establish and maintain the biological filter when adding new fish.   

Directions for Use:

• Use 1 capful (5 mL) per 200 L (50 US gallons) of new water.   
• For smaller volumes, note that each cap thread equals approximately 1 mL.   
• Preferred Method: Add to new water before introducing it to the aquarium.
• Direct Addition: If adding directly to the aquarium, base the dose on total aquarium volume.   

A sulfur odor is normal and indicates product activity.   

• For high chloramine concentrations, a double dose is safe.
• In emergencies to detoxify nitrite, use up to 5x the normal dose.   
• If water temperature exceeds 30°C (86°F) and chlorine or ammonia levels are low, use a half dose.
