1.026

Which is a better overall salinity for fish, 1.024 or 1.026 and why?

Are you properly calibrating your refractometer? Lot of people just use RO/DI water which will read 0..however your not going to get the the most accurate results. the next batch of people will use proper 35ppt/1.026 calibration solution which gets you closer.. but ar you taking into account...
