All In One 500ml/16fl.oz from TMC
All in One makes 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, the skeletal material of hard corals and the skeletal needles of soft/leather corals.
Growth and multiplication of these organisms means depletion of those substances.
Trace elements are also very important as explained above.
Salifert's All in One supplement is highly concentrated and contains approx. 35000 ppm calcium, corresponding amounts of biologically-activated bicarbonate and 700 ppm strontium.
The calcium is acetate based and, unlike gluconate-based products, is converted within minutes to calcium bicarbonate.
Occasionally an additional boost of alkalinity with Salifert's KH+pH buffer is recommended to compensate for alkalinity lost by, for example, decaying food. Iodine should also be supplemented for the best result.
