Have Questions About Seachem Conditoners?
We have answers. Get quick help for common questions.
What is Seachem and why is it trusted by aquarists?
Seachem is a globally recognised brand that has been providing scientifically formulated aquatic care products since 1980. From water conditioners and filtration media to reef supplements and plant fertilizers, Seachem’s product line covers nearly every aspect of freshwater and marine aquarium care. The brand is known for its lab-tested quality, consistency, and effectiveness, making it a top choice among both beginner and advanced hobbyists.
What are the most popular Seachem products?
Seachem’s most recognized products include Prime, a water conditioner that removes chlorine, chloramine, and detoxifies ammonia; Stability, which introduces and supports beneficial bacteria for biofiltration; Purigen, a synthetic resin that removes organic waste and enhances water clarity; Reef Fusion 1 and 2, a balanced two-part calcium and alkalinity system for reef tanks; Matrix, a premium biological filter media; and Flourish, a staple nutrient supplement for freshwater planted aquariums.
Can I use Seachem Stability with an established tank?
Yes, Seachem Stability is not limited to new tank setups. It is extremely useful in established tanks for reinforcing the biofilter after events like filter maintenance, medication use, or water parameter changes. Regular use helps maintain microbial diversity and ensures stable biological filtration.
Is Purigen reusable, and how do I regenerate it?
Yes, Purigen is designed to be regenerated. When it darkens from white to brown or black, it can be soaked in a bleach and water solution (1:1 ratio) for 24 hours. After thorough rinsing, soak it in water treated with Seachem Prime to neutralize residual chlorine. Once complete, it can be reused multiple times. Never use Purigen in tanks treated with copper-based medications.
How do Seachem plant fertilizers work in planted aquariums?
The Flourish line provides both macro and micronutrients for aquatic plants. Flourish Trace and Flourish provide essential elements, while Flourish Excel delivers bioavailable carbon. Seachem also offers focused nutrient products for nitrogen, phosphorus, potassium, and iron. These supplements are designed to support healthy growth, vivid colouration, and long-term aquascaping success.
Are Seachem products safe for shrimp and invertebrates?
Most Seachem products are safe for use in shrimp and invertebrate tanks, including Prime, Stability, and Flourish. Always read the label for any exceptions. Products like Cupramine, which contain copper, should not be used in invertebrate systems.
Where can I get dosing help or product guidance?
You can contact the Charterhouse Aquatics customer support team for detailed help on selecting and using Seachem products. Additionally, the official Seachem website offers product calculators, compatibility charts, and technical guidance. For more advanced systems, Seachem’s customer service can provide personalized support.
What types of aquariums can Seachem products be used in?
Seachem offers solutions for freshwater, planted, brackish, marine, and reef aquariums. Whether you’re managing a tropical freshwater community tank, a high-tech aquascaped planted setup, or a demanding SPS reef system, Seachem has targeted solutions that support water stability, nutrient control, biological cycling, and trace supplementation.
How do I use Seachem Prime correctly?
To use Seachem Prime, dose 5 mL per 200 litres of new or treated tap water. It should be used during water changes or anytime ammonia, nitrite, or heavy metals may be present. In emergency situations, up to five times the recommended amount may be safely used to detoxify harmful compounds and protect aquatic life.
What is the difference between Reef Fusion 1 and Reef Fusion 2?
Reef Fusion 1 provides calcium and essential ions that support coral growth and skeletal development. Reef Fusion 2 contains carbonate and bicarbonate to maintain proper alkalinity and pH levels. Both should be used together in equal parts to provide a balanced, two-part supplement system ideal for reef aquariums.
Are Seachem products reef-safe?
Seachem offers a specific marine product line that is reef-safe and compatible with sensitive corals and invertebrates. Products such as Reef Fusion, Reef Builder, Reef Calcium, and PhosGuard contain no harmful substances and are free from phosphate, nitrate, or unbound metals. When dosed according to instructions, they support reef systems safely.
Can I use multiple Seachem products at once?
Yes, Seachem products are formulated to work in harmony. However, it’s important to follow dosing guidelines and avoid combining them with incompatible products. For example, Prime should not be used simultaneously with oxidising medications. Refer to Seachem’s compatibility resources or contact their support team for custom advice.
Where are Seachem products made?
All Seachem products are manufactured in the United States. The company is privately owned and independently operated, with a strong reputation for in-house research, quality control, and consistent product formulation.
