Freshwater/Brackishwater/Marine
At what salinity is water considered FW, BW or MW?
The reason I asked this is because when I researched the knight goby, I found that it prefers Freshwater, however, It also cannot tollerate PURE freshwater, and requires some salt (around 1.001-1.005 specific gravity) so, I was wondering if this salinity is considered brackish or fresh, and where the drawing line is, I understand the drawing line for Brackish and Marine to be 1.020-1.025, so what about freshwater and brackish water?
Many people add some 'aquarium salt' to their aquariums, but that doesn't make them BW, so the term 'somewhat salty' is a little too vague...........
