I ran coral pro for a year and a half in my 54 gallon corner. Finally ordered my test kit and my alk was at 14!!! I have since changed to blue bucket salt and am slowly bringing that number down. In the course of 3 weeks with a weekly water change of 20%. I have brought alk down from 14 to 11.9... Slowly working my issue out...
Now I would check my calcium if I were you right before my water change, see if they are up taking it... And I would STRONGLY caution dosing with the coral pro salt... Think that salt is for large aquariums packed with mature colonies of sps and encrusting lps... That's just my opinion on it, hope it helps!
