  • Mix the ingredients with care because an exothermic reaction will occur. In other words, the combination will release heat.
  • After mixing, the water will become clear.

The next step is to mix the new solution with the ground charcoal. But first:

  • Mix the charcoal and the solution. The chemical will activate the charcoal.
