Ensure the pristine health and safety of your aquatic environment with Seachem Prime® – the complete and concentrated water conditioner designed for both freshwater and saltwater aquariums! Prime® is your essential first step for setting up a new tank and a vital aid for every water change, neutralizing harmful elements and creating a healthier home for your aquatic inhabitants.
This powerful solution goes beyond basic conditioning. It actively removes chlorine, chloramine, and ammonia. Uniquely, Prime® converts ammonia into a safe, non-toxic form that is readily removed by your tank's biofilter. It also effectively detoxifies nitrite and nitrate, allowing your biofilter to work more efficiently, and will even detoxify any heavy metals present in your tap water. Use it at start-up and whenever adding or replacing water to maintain a clean, safe, and thriving aquatic ecosystem.

Detoxifies Ammonia: Converts toxic ammonia into a safe, non-toxic form, which is then easily removed by the tank's beneficial bacteria (biofilter).

Q: I think that my Prime® might be old because it smells like it went bad.
A: Prime® has a very distinct odour that is often described as similar to sulfur. This smell is completely normal and is an indication that the product is working as intended due to its active ingredients.
Q: I noticed some small black specks in the bottom of my bottle of Prime®. Is it still good?
