By salt, Im guessing that is calcium... Thats high for cal.
dKh at 7.2 is low......test the new water befor adding and if its better than your reading in the tank then just do water changes and dont do any additives
Good water with cal. around 430 ppm and Alk. around 3.5 meq/L is best but dont try to get it perfect too fast. Just get it better and see how it goes... The better the alk. and cal gets to a better balance then the pH should raise to a better higher level and stay more stable...
