Product description

Size :50 ml (Pack of 1)

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. 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.


From the manufacturer

Important information

Ingredients

Be very careful when purchasing water conditioners. If your municipality includes chloramines in the water supplies, a standard sodium thiosulfate dechlorinator is not enough. Prime® promotes the natural production and restoration of the slime coat rather than relying on artificial or non-native slime compounds. A further bonus for the reef hobbyist—Prime® will not overactivate protein skimmers.

Directions

Use 1 capful (5 mL) for each 200 L (50 US gallons) of new water. For smaller volumes, please note each cap thread is approximately 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 Gold standard for water conditioner hands down
By Christopher Cook on May 13, 2019
As a fish hobbyist this is pretty much the gold star for treating aquarium water when doing water changes. Having multiple aquariums i can use it in premix buckets or drill a small hole in lid and squirt a bit in the tank directly as im filling straight from tap. Also very handy when i had 35 new cichlids given to me and didnt have a tank cycled and ready for them so it was water changes everyday and prime to control any ammonia spikes and to dechlorinate my tap water a double bang for the buck. Never overdosed or had issues with hurting my fish. And i found that i could half my bottle into another one top with water and still use it as directed and in 2 years and 7 tanks never had a issue. Great product and arrived fast and price same as my local fish store is. Gotta have this I'm telling you.

4.0 out of 5 stars Broken Seal?
By Terri W on May 26, 2021
*Update: Received a new one as replacement,
and the seal was intact and super hard to get off like usual. Happy with the replacement!

Broken seal. I had some left in my old one and it DOES NOT SMELL the same. Expired?
It's almost like a dirty water diluted Prime.
The seal looked neatly pulled back half way.
Cap was slightly ajar and the packaging was dry.
I wouldn't trust this with the life of my aquatic critters. No way.
The other two seachem products Excel and Phosphorus were sealed and in great condition.
