Seachem Prime 500ml – Complete Water Conditioner for Fresh & Saltwater

Seachem Prime® 500ml is a highly concentrated, all-in-one water conditioner designed for both freshwater and marine aquariums. It instantly removes chlorine and chloramine while detoxifying ammonia, nitrite, and nitrate—making tap water safe for fish and invertebrates.

Prime® converts toxic ammonia into a non-toxic form that can be safely processed by the aquarium’s biological filter. This makes it especially useful during tank cycling, water changes, or emergency ammonia spikes. In addition, Prime® detoxifies heavy metals commonly found in tap water and promotes the production and regeneration of the fish’s natural slime coat for improved health and stress resistance.

Its non-acidic formula does not affect pH and will not cause protein skimmers to overactivate, making it safe and reliable for daily use in reef, marine, and freshwater systems.
