it’s true that currently you cannot change the water type (was: salinity) of a 
dive downloaded from a computer, you can only use the value provided by the 
computer. This is a) because nobody has implemented a user interface to change 
it and b) (more importantly) because the water type is not so much about how 
salty the water tasted but how to convert ambient pressure (which is what the 
dive computer actually measures) to depths and back. But what the computer 
reports is depth and for the calculations (like SAC and the deco stuff) we 
again need the ambient pressure. So this is off if the dive computer and 
Subsurface do not agree on the conversion factor. So even if you were diving is 
sea water and your dive computer was set to fresh water (or missing that 
setting not set at all) it would still be better to log this as fresh water in 
Subsurface (to get the conversions right) than to manually set that to salt 
water (or we would have to correct the depths accordingly).
