(2) Testing Equipment:
(a) All public swimming pools shall have functional test kit(s) or equipment for measuring the pH, free and combined chlorine concentration, or bromine, (or concentration of other approved disinfectant), total alkalinity, turbidity (water clarity) and cyanuric id if stabilized chlorine is used;
(b) Functional test skits or testing systems to test for total copper and silver concentrations shall be provided when they are used as supplemental disinfectants;
(c) Test kits for measuring free chlorine or bromine shall use DPD as the reagent.
(3) Pool operators shall test and record the parameters described in subsections (2)(a) and (b) of this rule with the following minimum frequencies during periods when the pool is open for use:
(a) pH -- Daily;
(b) Chlorine:

(A) Outdoor Pools -- Bromine -- Hourly;
(B) Indoor Pools -- Bromine -- every 4 hours.
(d) Continuous reading devices shall satisfy requirements in subsections (3)(a), (b) and (c) of this rule if such devices record in pH units and ppm of free chlorine or bromine;
(e) Total copper -- Weekly, if used;
(f) Total silver:
(A) If ionizing technology is used, once per quarter for one year after equipment is installed; twice per year thereafter;
(B) Weekly if silver is dispensed without using ionizing technology.
(g) Total alkalinity -- Weekly;
(h) Calcium hardness -- (recommended) -- Weekly;
(i) Turbidity -- Daily;
(j) Cyanuric acid (if used) -- Monthly.
