The sea salt is dissolved according to the normal ratio of 1:30. Generally, the water pump is needed in the dissolution process to make the water move that will greatly reduce the time of dissolving. 6.7kg sea salt dissolved 200L fresh water, and the complete dissolution time is within 15 minutes.

The sea salt just dissolved is not stable, and the pH value is about 8.4. It is best to use pure water or softened fresh water, and the hardness should not be too high.

According to this ratio, the specific gravity of seawater is between 1.023 and 1.025. After 12 hours of water circulation, the pH begins to fall back to around 8.1 that can be used.

If the dissolution is slow according to this ratio, the water is turbid, which may be caused by the hardness of the fresh water being too high.

Because the components in the sea salt are balanced, regardless of other components in the fresh water, the high carbonate content in the fresh water reacts with the calcium in the sea salt to form a precipitate.

For example, in some areas, the autumn and winter seasons have less rainfall, so the carbonate content in groundwater is relatively high, which is likely to cause slow and turbid.  Therefore, it is best to dissolve the carbonate hardness of fresh water (1-6 °dH) before.

Another phenomenon is that the proportion of salt is not proportional to 1:20, 1:15, 1:10, and it is difficult to dissolve.
