Seachem Prime Water Conditioner – Complete Tap Water Conditioner for Freshwater & Marine Aquariums

Seachem Prime® is one of the most trusted and concentrated aquarium water conditioners available, providing complete protection for both freshwater and marine fish. Designed to instantly remove chlorine and chloramine while detoxifying ammonia, nitrite, and nitrate, Prime helps create a safe environment for fish during water changes, tank cycling, transport, and emergencies.

Unlike many standard dechlorinators, Seachem Prime actively detoxifies harmful compounds without removing them from the biological filtration process, allowing beneficial bacteria to continue processing waste naturally. Prime also enhances the natural slime coat of fish, helping reduce stress and support recovery from handling, transportation, and environmental changes.

Whether you're maintaining a tropical community tank, goldfish aquarium, planted aquarium, cichlid setup, or marine reef system, Seachem Prime is an essential part of aquarium care.

Why Use Seachem Prime?

Tap water often contains chlorine and chloramine that can be harmful or fatal to fish and beneficial bacteria. Prime neutralises these chemicals instantly while also detoxifying toxic ammonia, nitrite, and nitrate, helping keep your aquarium inhabitants safe and healthy.

Its concentrated formula means a small amount treats a large volume of water, making Prime one of the most economical and effective aquarium water conditioners available.

Creature Culture Tip

Keep a bottle of Prime on hand for emergencies. If you experience an unexpected ammonia spike, fish stress event, or filtration issue, Prime can temporarily detoxify harmful ammonia and nitrite while you address the underlying cause.
