Complete conditioner for both marine and freshwater use
Safely condition water without a pH drop or overactivating protein skimmers
Provides essential ions and stimulates natural slime coat
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 and nitrite. 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 overactivate protein skimmers. Great for setting up new aquariums, or when adding or changing water, or to remove nitrate. Use 1 ml for each 35 litres of water. For freshwater or saltwater use. 100 ml treats 3,750 litres; 250 ml treats 9,500 litres; 500 ml treats 19,000 litres
Directions for Use:
Use 1 capful (5 ml) for each 50 gallons of new water. For smaller doses, please note each cap thread is approximately 1 ml. This dose removes approximately 0.6 mg/L ammonia, 3 mg/L chloramine, or 4 mg/L chlorine.
May be added to aquarium directly, but better if added to new water first. If adding directly to aquarium, base the 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 > 86°F and chlorine or ammonia levels are low, use a half dose.
Principal Ingredients: Bisulfites and hydrosulfites, aqueous solution, buffered at pH 8, with ameliorating ingredients. Reducing agents.
Frequently Asked Questions regarding Prime:
Q. My Prime smells like it went bad, is it ok to use it?
A. Yes. While Prime has a very distinct odor that is similar to sulfur, this is completely normal and does not affect the performance of the product. The presence of small black specks is also normal.
Q. I am using Prime to control ammonia but my test kit says it is not doing anything; in fact, it looks like I added ammonia, what is going on?
A. To avoid false readings of ammonia, use Seachem's MultiTest Ammonia kit (item #901231). It uses a gas exchange sensor system that is not affected by the presence of Prime or other similar products. It also has the added advantage that it can detect the more dangerous free ammonia and distinguish it from total ammonia (which is both the free and ionized forms of ammonia (the ionized form is not toxic).

This is another product by Seachem that is a must for all fish keepers this product has been a life saver at times i had a few of my tanks go into mini cycles and this helped get the fish through the raise in ammonia and nitrite as it detoxify them to make the water safe for fish it always lasts a long time because it is concentrated I would highly recommend this product.
