Artificial Sea - Salt

The product is intended primarily for use in lobster and crab holding systems, the salt contains the five main constituents making up sea-water. A trace element solution can also be purchased separately to be added to the artificial sea-water.

The product is supplied in 16 kg sacks and the entire contents of a sack should be used when making up the artificial water. If only part of a sack is used the correct chemical balance of salts will not be achieved.

One of the 16kg sack of salt will make up 500 litres of artificial sea-water at 32ppt, salinity and gravity hydrometers are available for checking the salinity of the water.

Seawater has an extremely complex chemistry, however a relatively few constituents make up the bulk of the components. The pie chart and table below present the main components.

Salt,  sodium chloride

Ordinary salt (sodium chloride) is one of the main constituents of the artificial sea-water and is available as a separate product. An important consideration is that most salt available in the UK and elsewhere contains an anti-caking agent made from a stable form of cyanide. The salt is perfectly safe to use in most ways, however in aquaculture it can actually be very toxic. For example if the salt is dissolved in water and then exposed to UVc light (as it is in mussel depuration units), then the cyanide is released into the water in its free form. Obviously this is not a desirable situation, therefore all of the salt supplied by Dryden Aquaculture, and all salt used in the Artificial Sea-Water is free from anti-caking agents and cyanide.
