Protect your aquarium and keep your fish thriving with Seachem Prime 500ml, a complete and highly concentrated water conditioner for both freshwater and saltwater systems. Trusted by hobbyists and professionals alike, Prime removes chlorine and chloramine while detoxifying ammonia, nitrite, and nitrate—creating a safe and stable environment for your aquatic life.
Unlike basic dechlorinators, Prime actively binds harmful compounds, making them non-toxic and easier for your biological filtration to process. It’s especially valuable during tank cycling, water changes, or emergency ammonia spikes—helping reduce stress on fish and prevent damage to your system.
Reef-safe and non-acidic, Prime will not disrupt pH or interfere with protein skimmers when used correctly, making it ideal for sensitive reef aquariums.
