Seachem Prime Complete & Concentrated Water Conditioner

The one bottle every aquarium needs. Seachem Prime is a complete, highly concentrated conditioner that makes tap water safe for fish the moment you add it. It removes chlorine and chloramine and detoxifies ammonia, nitrite, and nitrate, so fresh water and mini-cycles will not harm your fish. It also binds heavy metals such as copper and lead. One capful treats a lot of water, which is why a small bottle lasts so long.

Safe for freshwater, saltwater, and reef aquariums. Stock up alongside the rest of our water care and aquarium essentials .
