Boron is very important in marine environments. Too low a concentration can slow down the growth of coral and too high can be dangerous to the health of aquarium inhabitants.
Boron concentration in natural sea water is relatively low, between 4.4 mg/L and 4.8 mg/L.
Regular boron testing is advisable if you are dosing with a Boron supplement.
The Salifert Boron Profi-Test kit easily measures the level of naturally occurring boron in steps of 0.5 mg
