The less obvious requirements are
  • Testing - pH test with phenol red, a very simple test, 6 drops in the test tube, compare to the chart.

Most pools creep the pH up, so add acid to bring down to 7.2

  • Chlorine test, 6 drops in the test tube, compare to the chart. Ideal level 0.8 - 1.0
  • ALGIBLOC. This copper based product kills algae and will last up to 6 months. Most of the recommended dosage of chlorine in the pool, is to kill algae.

When ALGIBLOC is used to control the algae, you only need to add chlorine when you're going to swim and then only at low levels.
