Seachem Prime 1 L — Ultra-concentrated aquarium water conditioner

Seachem Prime 1L is the ideal value pack for serious aquarists who use Prime regularly. A single 1-liter bottle treats up to 20,000 liters of water —the best value in the entire Prime range. If you perform weekly water changes on a large system or manage multiple aquariums, this is the size to choose.

Same ultra-concentrated formula as other formats — the most used and recommended water conditioner in the world by professional and passionate amateur aquarists.
