The Tropic Marin Nano Shake & Make is an original salt-mixing kit which combines the best ideas of both the Instant Ocean commemorative jug set and the Seachem Hydrotote. Not only is the Tropic Marin Nano Shake & Make a collapsable jug, it also is paired up with pre-measured amount of salt mix to create a perfect salinity within the volume of the Shake & Make’s jug.

The Nano Shake & Make costs “about the same price” as a Seachem Hydrotote but it comes pre-filled with with the right amount of Tropic Marin salt to mix 2.5 gallons, 10 liters of water 1.025 to 1.027 at a temperature between 73 to 77°F (23-25°C).
