The Head Start Conditioner Pack brings together three of Seachem's best-selling water conditioners: Prime, Stability, and Clarity (100ml bottle of each). Prime is a complete and concentrated conditioner for both fresh and salt water. It should be used when setting up a new tank, adding, or changing water. It removes chlorine, chloramines and converts ammonia into a safe, non-toxic form. Stability will rapidly and safely establish the aquarium biofilter in freshwater and marine systems, preventing fish death by "new tank syndrome". It contains a synergistic blend of aerobic, anaerobic, and facultative bacteria which facilitate the breakdown of waste organics, ammonia, and nitrate. Clarity is the ultimate clarifier for both fresh and salt water. It employs an advanced polymeric flocculating agent that is both reef and plant safe, and will clear all types of clouding.
