Protect your chlorine from sunlight with our Pool Stabilizer range. Pool stabilizer (also called chlorine stabiliser or CYA) helps reduce chlorine loss caused by UV exposure, which is especially important for outdoor pools in strong sun.
When stabilizer levels are in the correct range, chlorine lasts longer and sanitation becomes more consistent—helping you avoid rapid chlorine drop-offs and unnecessary over-dosing.

When to use stabilizer (CYA)

Use stabilizer if:
  • Your chlorine drops quickly in sunny weather
  • You’re topping up water often and CYA is low
  • You’re setting up a new outdoor pool
Best practice:
  • Test CYA before adding more (too much stabilizer can reduce chlorine effectiveness)
  • Dose according to pool volume and label directions
  • Retest after circulation to confirm you’re in range
