CyA Test Tablets for Cyanuric Acid

Overview

Cyanuric acid tablets measure cyanuric acid, the stabiliser that protects chlorine from ultraviolet light in an outdoor pool. Too little and the chlorine burns off in a day of sun; too much and it holds the chlorine so tightly that the residual stops working, which is why the level is checked rather than assumed.

Key features

• Controls pool stabiliser level, which decides how hard the chlorine works
• One tablet per test, so there is no measuring or decanting of liquid reagents
• Foil-sealed strips keep unused tablets dry until they are needed
• Supplied in the standard 250-tablet pack, item code TbsPCAT250

Frequently asked questions

What happens if cyanuric acid gets too high?
The stabiliser binds the chlorine so effectively that disinfection slows, a condition often called chlorine lock. The remedy is dilution, since cyanuric acid is not consumed.

Photometer grade or rapid grade — which do I need?
Photometer grade is formulated for instruments that read a cuvette. If you work with a visual comparator or colour disc, ask us for the rapid-dissolving grade instead.

How should the tablets be stored?
Keep them sealed, cool and dry, and work through the oldest strip first. Once a strip is opened the tablets take up moisture, so use them promptly.
