    I'm going to put a regal angel through hypo in the QT tank he's currently in. I'm aiming for about 11-13 ppt but I'm not quite sure how I should calibrate my refractomer. I'm reading 10-11 ppt if I calibrate off of my 35 ppt solution but read 15 ppt if I calibrate off of RO. Should I try to do something weird like weight the readings 2/3 on the RO calibrated reading and 1/3 on the 35 ppt calibrated figure?
