Reasons for high calcium and magnesium levels after chelation

Every time the resin tower is cut, the calcium and magnesium levels measured are much higher than before the cutting. For example, yesterday, the calcium + magnesium level in the main tower was around 9 before cutting, but after cutting it rose to over 16. What exactly causes this? # + + .
The increase in calcium and magnesium after cutting indicates that the regeneration tower contains large amounts of these elements; the possible reasons are reduced adsorption capacity of the resin, incomplete acid washing, incomplete displacement, and too low pH value of the brine…
