Cloudy or green water: what it means and how to fix it

Cloudy or green water is alarming, but it almost always has a simple explanation: wrong chemistry, too few filter hours or a dirty filter. The pool doesn't need draining.

  • pH first, then chlorine
  • Filter running non-stop until it clears
  • Brushing to loosen algae

Step-by-step clean-up

  1. Empty the baskets and backwash the filter.
  2. Bring pH to 7.2–7.4.
  3. Raise chlorine temporarily, following the product instructions.
  4. Brush walls, steps and floor.
  5. Run the filter non-stop until the water clears, backwashing in between.
  6. Vacuum whatever settles on the floor.
Don't drain the pool to "clean" it. A liner pool needs the weight of the water, and draining doesn't fix the cause.

To stop it happening again

  • More filter hours in hot weeks.
  • Paving that falls away from the pool, so soil doesn't wash in. See surround.
  • Steady disinfection with salt or an automatic feeder.
  • A cover when the pool isn't in use.

When the level keeps dropping

In summer, evaporation can take a few centimetres a week. But if the level drops much faster, or stops dropping at a certain height, there may be a leak at a fitting or a pipe. Send us photos on WhatsApp.

Questions

Can I swim in cloudy water?

Better not, because you can't see the floor and disinfection may be inadequate. Wait until it clears.

How long will the clean-up take?

From a few hours for slight haze to a few days for very green water, depending on the filter.
