All in One is a high quality supplement. It contains almost everything required for growth by corals, and encrusting pink and red coralline algae.
All in One will increase the alkalinity (carbonate hardness), calcium, strontium, trace elements (except iodine) and amino acids concentrations. These elements are required by corals to encourage healthy growth and development. Calcium, strontium, carbonate (alkalinity) and amino acids are the major constituents of calcareous algae, skeletal material of hard corals and the skeletal needles of soft/leather corals. Growth and multiplication of these organisms means depletion of those substances.
The trace elements included in All in One allow organisms to carry out many biological processes that are essential to health and vitality.
