Brightwell Aquatics BoroChrom 500mL. The importance of boron to reef-building organisms is most apparent when beginning to dose it in aquaria with depleted boron concentrations, and/or in which the sea salt mixture employed is boron-deficient; in such cases, changes in the rate of coralline algae growth, as well as in the appearance of many corals, may be observed within the first weeks of daily dosing.
