For the launch of a new aquarium, we advise to put the first animals in it only after 10-14 days from its filling. Seawater freshly prepared by dissolving salt can be immediately used for a partial water change.
Method of preparation: the salt must be dissolved in previously prepared demineralised water. The water temperature should be around 24°C (75°F). To obtain a salinity of 31 PSU
(~1.024 SG), approximately 3.8 kg (8.4 lbs) of salt should be dissolved in 100 l (22 US gal.) of water. The solution should be vigorously mixed for about 15 min. Once dissolved, the salty water is ready for use.
Salt should be kept in a dry place, away from light and moisture. The dissolved salt can be used for 5 days.
Keep out of reach of children. To be used only for aquariums. Cannot be consumed by humans.
