About iron
About 6.3% of the earth’s crust is made of iron with 43% of this amount held in the soil. As a result, iron is naturally present in most water supplies.
Left in the water, iron will stain pipework and swimming pool, hot tub and spa surfaces, causing brown spots, cloudiness or brown water.
Testing should therefore form an important part of any water monitoring process in your swimming pool, hot tub or spa with the maximum concentration of iron in a bath being 0.2 mg /L.

| PLEASE NOTE: | In some cases, samples may contain other parameters which may interfere with results | |
| Interferences may be caused by: | Alkalinity: above 2,000 mg/L (as CaCO3). May slow down colour development (negative error). To resolve this, neutralise the sample with diluted HCl. Calcium (Ca2+): above 10,000 mg/L as CaCO3 Copper (Cu2+): does not interfere: reagent contains a masking agent. Magnesium (Mg2+): above 100,000 mg/L as CaCO3 Molybdate Molybdenum: above 25 mg/L (as Mo-MoO4) (positive error) Sample containing up to 50 mg/L Mo-MoO4 may be measured if a reading is taken after 1 minute instead of 3 minutes. High Iron concentrations up to 200 mg/L do not inhibit colour development; above 200 mg/L colour development may be inhibited. High sulphide concentrations (S2-): high sulphide concentrations may interfere. To reduce sulphide: acidify the sample and boil for about 20 minutes, neutralise and adjust volume before measurements. Silica (SiO2): above 175 mg/L (as SiO2). May slow down colour development (negative error) |
