high levels

Hello all soon trying to figure out why my mag levels are so high and calcium levels I have done a water change and added rodi water to help with salinity’s levels here are my levels

Hello, I would like to keep my macros on levels similar to Red Sea Coral Pro Salt (Ca 465, Mg 1390, kH 12) + raising pH to levels between 8.2-8.5 depending on the timeframe. Of course such levels significantly increase precipitation of minerals such as calcium. What can be done to prevent it...
