• Calcium (Ca) Accuracy / Precision (+/-): 6 mg/l / 6 mg/l.

These are the building blocks for the reef system and reefers aim to achieve a balanced level together with alkalinity.  These two elements reacts slower than alkalinity and therefore regular measurements of Ca and Mg 2-3 times a week with keeping it in par will be sufficient but it is important to keep the BIG 3 (KH, Ca, Mg) in balance to achieve good growth and coloration.

• Magnesium (Mg) Accuracy / Precision (+/-): 20 mg/l / 20 mg/l

These are the building blocks for the reef system and reefers aim to achieve a balanced level together with alkalinity.  These two elements reacts slower than alkalinity and therefore regular measurements of Ca and Mg 2-3 times a week with keeping it in par will be sufficient but it is important to keep the BIG 3 (KH, Ca, Mg) in balance to achieve good growth and coloration.

• Alkalinity (dKH) Accuracy / Precision (+/-) 0.1 dKH / 0.05 dKH.

Alkalinity (dKH) is the main element that is fast changing in a matter of hours.  Just by monitoring dKH, you can know if other equipment is functioning correctly or not. 

1) Calcium Reactor pump failing

2) Doser not running correctly

3) Lights not turned on (lights triggers dKH consumption)

4) Unbalanced of other elements (Mg/Ca)
