Seachem Prime 100 mL — Ultra-concentrated aquarium water conditioner

Seachem Prime 100 mL is the ideal entry-level size to discover the world's most recommended water conditioner. It features the same ultra-concentrated formula as the larger sizes—one 100 mL bottle treats up to 2,000 liters of water at the standard dosage of 5 mL per 200 liters.

It's the perfect size to start a first aquarium, test Prime before buying a larger size, or have a spare bottle on hand at all times.
