Seachem Prime
Seachem Prime is the most trusted water conditioner in the aquarium hobby. A single concentrated dose instantly removes chlorine and chloramine from tap water while detoxifying ammonia, nitrite, and nitrate, making it safe for fish during water changes and emergency spikes. Because it is so concentrated, a small bottle treats a large volume of water, making Prime both effective and economical for freshwater and saltwater aquariums alike.
Seachem Stability
Seachem Stability builds and maintains a healthy biological filter, helping you cycle new aquariums quickly and safely. Its blend of beneficial bacteria establishes the nitrogen cycle to break down ammonia and nitrite, reducing the risk of "new tank syndrome" and dangerous water-quality crashes. Stability is also ideal after water changes, filter cleanings, or adding new fish, whenever your beneficial bacteria need a boost.
Seachem Purigen
Seachem Purigen is a premium synthetic filtration media that polishes aquarium water to exceptional clarity. It removes organic waste, tannins, and discoloration before they break down into nitrogen compounds, helping control ammonia, nitrite, and nitrate. Purigen is reusable, can be rinsed and recharged, and visibly changes color as it exhausts, so you always know when it is time to renew it.
Seachem Flourish
The Seachem Flourish line provides complete nutrition for planted freshwater aquariums. Flourish supplies essential trace elements and micronutrients, Flourish Excel offers a bioavailable carbon source for lush plant growth, and specialty supplements like Flourish Trace, Iron, and Potassium target specific deficiencies. Together they support vibrant, healthy aquatic plants in everything from low-tech setups to high-light aquascapes.
Seachem Matrix
Seachem Matrix is a high-capacity biological filtration media designed to provide enormous surface area for beneficial bacteria. Matrix supports both aerobic and anaerobic bacteria, helping reduce ammonia, nitrite, and nitrate while maintaining a stable biological filter. It is suitable for canister filters, hang-on-back filters, sumps, and other filtration systems.
