So I recently bought a handheld Refractometer, the seller at the LFS calibrated it for me.
I'm a newbie and it didn't occur to me ask how he calibrated it. Now I'm at home and I want to know how its done properly as I will start my tank cycle soon.
The manual that came with Refractometer says calibrate it to 0, however, from youtube and general googling, a lot of people calibrate it to 35 ppt.
Which one should I go for?
