Who Is This For?

Seachem Prime is essential for every aquarium owner who uses tap water. Whether you have a 5-gallon betta tank or a 200-gallon community aquarium, Prime should be used during every water change. It is particularly critical for fishkeepers in areas with chloramine-treated water, during tank cycling when ammonia spikes can occur, and in emergency situations where ammonia or nitrite levels become dangerous. New fishkeepers should consider Prime a mandatory first purchase alongside their aquarium, and experienced hobbyists already know it is the best conditioner available.
