Chemical Level Check

Always check the chemical level of your pool because doing the job with imbalanced water will only cause you more time, money, and longer process.

  • You can use either pool a testing strip or tester kit for more accurate result but with quite complicated step.
  • Make sure that the chemical level is between the ideal range which is:
    pH: 7.2 – 7.6, so if your water level is lower or higher than this, the chlorine won’t be able to work well.
    Cyanuric acid: 20 – 50 ppm (parts per million). This helps chlorine to sanitize the water.
    Free chlorine: 1 – 3 ppm. If it’s below this number, algae can grow freely in the water.

Add the Bleach

The basic rule is that 10,000 gallons of water will need around 8 quarts of bleach. Before starting the job, please make sure:

  • Choose the right time. We recommend doing the job around the evening since excessive sunlight exposure may break the concentration of the bleach.
  • Add the bleach slowly over the return jet of your pool. You don’t need to dilute the bleach.

Check and Wait

Once the bleach is added to the pool, you can wait for the result for around 1 to 3 days depending on the severity of the problem. At the same time, you also need to keep checking a few things like:

  • The chemical level of the water.
  • Scrubbing the floor and wall of the pool to clean the dead algae.
