About the Seachem Prime Water Conditioner F/W &S/W
PRODUCT DETAILS
• Product Size/Qty: 500 ml (16.9 oz)
• Product Count: 1
• Manufacturer: Seachem
• Pet Category: Ammonia Removers
• Product Category:
Seachem Prime is the complete and concentrated conditioner for both fresh and saltwater aquariums. Use during startup and water changes to eliminate and detoxify harmful chemicals in tap water and make your aquarium safe for fish.
* Removes chlorine, chloramine and toxic ammonia
* Detoxifies nitrite and nitrate
* Provides protective slime coat
Prime is safe for fresh and saltwater aquariums. It detoxifies ammonia, nitrite and nitrate, allowing the biofilter to more efficiently remove them. Use Sechem Prime to detoxify any heavy metals found in the tap water at typical concentration levels. Prime also promotes the production and regeneration of the natural slime coat. Seachem Prime is non-acidic, will not impact pH and will not overactivate skimmers.
Use at startup and whenever adding or replacing water. Prime may also be used during tank cycling to alleviate ammonia/nitrite toxicity.
Directions: Use 1 capful (5 ml) for each 200 L (50 gallons) of new water. This removes approximately 1 mg/L ammonia, 4 mg/L chloramine, or 5 mg/L chlorine. For smaller doses, please note each cap thread is approx. 1 ml.
Tips: 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.
