Seachem Prime Water Conditioner, 2 Liter

No other aquarium water-conditioning product is required to make tap water safe. Prime removes chlorine and chloramine (even in high chloramine levels), and detoxifies ammonia, nitrite, and nitrate. Provides essential ions and stimulates natural slime coat. Prime also detoxifies any heavy metals found in the tap water at typical concentration levels. When used during cycling, Prime enhances nitrate removal and does not cause a pH drop or over activate protein skimmers. Great for setting up new aquariums, or when adding or changing water, or to remove nitrate. Use 1 ml for each 10 gallons of water. For freshwater or saltwater use. 100 ml treats 1,000 gallons; 250 ml treats 2,500 gallons; 500 ml treats 5,000 gallons; 1 liter treats 10,000 gallons; and 2 liter treats 20,000 gallons.
