What to do when the level is too high?
Risks: disturbance of ionic balance, alteration of coral coloration, slowed growth.
Measures: perform regular partial water changes, check salinity, and slightly reduce the intake through Elementals K if you are using Balling Light (optimal value: 380–420 mg/L).
What to do when the level is too low?
Risks: tissue discoloration, insufficient growth, fragility of polyps.
Measures: gradually increase through Elementals K (spread the dosage over several days), monitor with a home test (AquaHomeTest K) and adjust to 380–420 mg/L.
