Hi. Did my first real ocean water change. Been using Red Sea coral pro first 12 months. Went to beach collected 150liters and took home to heat. Collection Water temp 18.5 sal 1.032. After heating. Temp 25.5. Salinity 1.029. Each if these readings were done with a calibrated refractometer. Why/ how does temp affect the salinity. ?? All other reading were spot on. Little light on cal but dosed to correct that.
