Product Description

Prime® is the complete and concentrated conditioner for both fresh and salt water. Prime® removes chlorine, chloramine and ammonia. Prime® converts ammonia into a safe, non-toxic form that is readily removed by the tanks biofilter. Prime® may be used during tank cycling to alleviate ammonia/nitrite toxicity. Prime® detoxifies nitrite and nitrate, allowing the biofilter to more efficiently remove them. It will also 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. Prime® is non-acidic and will not impact pH. Prime® will not overactivate skimmers. Use at start-up and whenever adding or replacing water. Nearly all companies manufacture a product that removes chlorine. None of those, however, can compare in quality, concentration, or effectiveness to Seachems flagship product: Prime®. Prime® is the second most concentrated dechlorinator on the market after our own aquavitro alpha™. A single 100 mL bottle will treat 1000 US gallons of tap water. Prime® will remove both chlorine and chloramines from municipal water supplies. Prime® also contains a binder which renders ammonia, nitrite, and nitrate non-toxic. It is very important to understand how those two functions work together. All dechlorinators operate through a chemical process known as reduction. In this process, toxic dissolved chlorine gas (Cl2) is converted into non-toxic chloride ions (Cl-). The reduction process also breaks the bonds between chlorine and nitrogen atoms in the chloramine molecule (NH2Cl), freeing the chlorine atoms and replacing them with hydrogen (H) to create ammonia (NH3). Typically, dechlorinators stop there, leaving an aquarium full of toxic ammonia! Seachem takes the necessary next step by including an ammonia binder to detoxify the ammonia produced in the reduction process.

Important Information

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. 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.

5.0 out of 5 stars The most effective water conditioner, November 18, 2007
This review is from: Seachem Prime 500ml (Misc.)
I usually don't write reviews, but I did want to take the time to recommend this product. I have been keeping fancy goldfishes for over ten years now and finding the right tap water conditioner had always been a headache for me. I have tried most of the popular products on the market and they have always given me either mixed results or no results at all. Too often, I've had the fish die on me after a water change. However, when someone recommended the Prime water conditioner to me during a visit to the pet store, my problem was solved. I have used this product for a few years now and never since had any more fish die after a water change. I sincerely believe this is the most effective all-in-one solution on the market and for regular fish keeping, this is the only water conditioner one really needs.

5.0 out of 5 stars Great Money Saver, February 1, 2008
By 
Angela (New York, USA) - See all my reviews
This review is from: Seachem Prime 500ml (Misc.)
In my opinion, SeaChem's Prime is the best water conditioner on the market. I've tried a few of them and Prime does the best job. It removes chlorine/chloramine and other toxic metals from water instantly. Plus, as little as literally ONE drop treats a gallon of water. I have a total of 115 gallons of water in my 3 tanks. I perform 50% weekly water changes in all of the 3 tanks. To give you an idea of how economical Prime is, I've had a 250 mL bottle of it for more than a year. Only a few dollars' worth will treat hundreds of gallons of water. And as I've mentioned above, I perform 50% weekly water changes for my 115 gallons of water. Now, that's what I call a really great product. Highly recommend it to any serious fish keepers :o)

5.0 out of 5 stars Best conditioner around, February 18, 2011
This review is from: Seachem Prime 500ml (Misc.)
I bought this water conditioner at a chain pet store. It is so effective at removing chloramines, chlorine, and ammonia that you barely need to use any at all. Just follow the directions and the bottle will last you forever if you have a modest sized tank.
