As a minimum, the average pool will want to keep the following chemicals on hand – even if you use a salt chlorinator, you will need these other pool chemicals from time to time:

  • Chlorine tablets and pool shock
  • Pool pH Up and/or pH Down
  • Test strips or test kit

Every pool will also need other chemicals to raise calcium, cyanuric or alkalinity levels, usually once per year – and clarifiers, enzymes, algaecides can be an important part of the overall routine or especially handy when you’re in a pinch!
