SwimsWithFish said:Quick question about pwc... Does the water you make for pwc have to have the exact same specific gravity of the dt?
carey said:It's the salinity, how much salt is in the water. I use a refractometer. Others use a hydrometer, the swing arm thing.
Sorry, whats specific gravity? How do you measure it?
kurtyboh said:the salinity, with a refractometer or a hydrometer
And refractometer is much better, right?
coffeetwitch said:its like a control. a fluid that is know to be a certain sg.
you test it like you would your water and then adj the refractrometer to it.
