I'd shoot for a lower number at first. If you raise your cal by 50 with mg that low it will find your alk and start to calcify on stuff. Your pumps will be the first thing it finds and it will seize them up. Raise your cal by 10 per day and let your tank figure out how it will wp effect it. If your coral are happy right now any dramatic swings will upset them. 50 in calcium in one day is quite a swing.

Maybe add cal and mg in the morning and test your alk in the evening and adjust if needed. Coral hate alk swings more than anything so you have to do this in baby steps....
