Salifert All in one 250ml

"All in One can make the use of the so-called A and B calcium and alkalinity supplements unnecessary It contains almost everything required for growth by corals and the beautiful 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. 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"
