Seachem Prime Water Conditioner
Seachem Prime® is a premium, highly concentrated water conditioner formulated for both freshwater and marine aquariums. More than just a dechlorinator, Prime® removes chlorine and chloramine while detoxifying ammonia, nitrite, and nitrate. Its unique formulation also binds heavy metals, making tap water safe for your fish instantly.
Unlike many competing products, Prime® is non-acidic and will not affect aquarium pH or over-activate protein skimmers in reef tanks. It’s up to 5x more concentrated than standard conditioners, making it a cost-effective and powerful choice for aquarists. Prime® is also ideal for tank cycling, as it helps reduce toxicity while supporting beneficial bacteria growth for a stable environment.
