Palintest Cyanuric Acid Pool Photometer Test Tablets – 250 Pack (AP087) for Stabiliser Level Testing

Palintest AP087 Cyanuric Acid tablets measure cyanuric acid (stabiliser / CYA) concentration in pool water using Palintest photometers and compatible photometric test systems. Cyanuric acid protects chlorine from UV degradation in outdoor pools — monitoring it prevents over-stabilisation, which reduces chlorine effectiveness. Each pack contains 250 individually foil-sealed tablets.

Frequently Asked Questions

What is the ideal cyanuric acid level for an outdoor pool?

The recommended cyanuric acid (CYA) range for outdoor pools is generally 30–50 ppm. Above 80–100 ppm, CYA begins to significantly reduce chlorine effectiveness (chlorine lock), making disinfection less reliable. Partial water replacement is the most effective way to reduce CYA that is too high.

Do indoor pools need cyanuric acid testing?

Indoor pools are not exposed to UV sunlight, so cyanuric acid is generally not required or used as a stabiliser. Cyanuric acid testing is primarily relevant for outdoor pools using stabilised chlorine products (such as trichlor or dichlor) or where cyanuric acid is added separately.
