Code
In AQUATIC VENUE water that contains cyanuric acid or a stabilized CHLORINE product, water shall be treated by doubling the inactivation time required under MAHC Section 6.5.3.1.
Annex
CHLORINE stabilizers such as cyanuric acid slow DISINFECTION; therefore, higher CHLORINE levels are likely necessary to reach the CT VALUE for Giardia inactivation in POOLS using CHLORINE stabilizers. However, at this time there is no standardized protocol to compensate for CHLORINE stabilizers and no data determining how the inactivation of Giardia is affected by CHLORINE stabilizers under POOL conditions. A SAFETY value of 2 has been incorporated until these data can be gathered.
