Default Ca and Mg calculations to increase GH. NEED HELP

Hi, I have a 55G tank probably around 50G water column. I need help calculating dry dosages of CaCL2 and MgSO4+7H2O needed to increase GH by 1, 2, and 3 degrees respectively. I would appreciate it if anyone can provide me with dosages for all 3 (preferably in grams). Also, should I dose only when I do my water changes (around 30%) or throughout the week? If I only need to dose them after water changes then I would prefer dry dosage calculations, but if it is better to dose throughout the week then I would prefer calculations of CaCL2 and MgSO4+7H2O diluted in 250ml. Thanks for your time your help is greatly appreciated.
