Colombo Marine Halo Complex Colour 1 contains iodine, bromine and fluorine.
These elements are important for especially pink colours.
Dosage after iodine test:
1 ml per 100 litres increase the iodine content with 0,03 mg/l.
Optimal value is 0,06 mg/l.
If you do not test the iodine content you can dose based on the calcium absorption. This method is less accurate and must be used with care.
