Prime is the complete and concentrated conditioner for both fresh and salt water...

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 tank’s 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.

Use 1 capful (5 mL) for each 200 L (50 gallons*) of new water. For smaller doses, please note each cap thread is approx. 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 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.

  1. Prime Product Review by jersysman

    Best water conditioner product on the market - bar none! Just dont smell it!! (Posted on 1/29/2012)

  2. When RO/DI isn't available, this can help Review by cmt

    Since I am on a strict Fish-tank budget, I can not afford a RO/DI unit...or to purchase pure water all of the time for my tank.

    Instead, I have been using Prime Water conditioner. This has done a great job at neutralizing the harmful things in my tap water and has kept my tank pretty clear from algae and my livestock healthy.

    I definitely would recommend this to other people looking to condition your water. I have been using it for 3 years now! (Posted on 2/4/2009)
