What is brackish water?
Brackish water is a mix of freshwater and saltwater.
It is saltier than fresh water, but not as salty as seawater. It may result from mixing of seawater with fresh water, as in estuaries, or it may occur in brackish fossil aquifers.
Technically, brackish water contains between 0.5 and 30 grams of salt per litre—more often expressed as 0.5 to 30 parts per thousand (ppt or ‰).
Thus, brackish covers a range of salinity regimes and is not considered a precisely defined condition. It is characteristic of many brackish surface waters that their salinity can vary considerably over space and/or time. Generally at Aquatic Solutions our brackish water species are kept at 10 -15 ppt salinity.

Here is a simple how to guide to make brackish water:
To make Marine Ocean Water: 1kg Sea Salt will make roughly 30L of ocean water (1.028) Brackish should be half rate of Marine Ocean water
Therefore brackish should be half rate, 1kg Sea Salt will make roughly 60L of brackish water (1.014)
