@aior0s, have you rechecked you alkalinity since recalibrating your refractometer? I use the Hanna salinity and temp checker and my salinity stays at 1.026. I started testing Alk yesterday for the first time and it came back at 6.1 Dkh too using the Hanna Alk checker.
Hey Kingston, I checked my new fresh made SW bucket and getting 7.0 @ 1.026 salinity.
I am going to check my DT after this. I change 10% of water yesterday
