Product: Salifert Profi Test KH / Alk - for 100 to 200 measuring
Calcium is not the only substance needed to form the skeletal material of corals and allow calcareous algae to grow.
The carbonate and bicarbonate is also needed and these two substances can have a marked effect on the establishment and buffering the pH.
The pH levels in the aquarium should be between 8.1 to 8.4.
The total carbonate and bicarbonate concentration are also called alkalinity or carbonate hardness and for a stable system the alkalinity should not fluctuate by 5% from the optimum level of approx. 2.8 meq / L ie a maximum fluctuation of 0:14 mEq / L.
The Salifert test is sensitive enough to discover the small changes in levels dell'alcalinità measured in steps of 0.1 meq / L
