What do pool test strips test for? （2）
Element | Test Range | Standard Range | Function |
MPS mg/L | 0.5-20 | 3-5 | MPS is short for Potassium Peroxymonosulfate. It can be used as an oxidizer for brominated pools and spas. To keep your spa water clean and healthy
|
QAC ppm | 0-40 | 5-10 | Algae inhibitor, algaecide |
Salt（NACL） ppm | 0-8000 0-1500 | 2000-4000 AUS 2700-3400 US 2000-6000 EU | Salt serves as a natural antiseptic, preventing the growth of bacteria and algae while causing no damage to swimmers' skin.
|
H2O2 ppm | 0-100 0-50 | 3-10 | Disinfectant |
Chlorine Dioxide ppm
| 0-10 0-500 | pool： ≤1 ＜2 drink：10-100 | Disinfectant |
Copper ppm | 0-1 | 0.2-0.4 | Disinfectant |
Phosphate ppb | 0-2500 | ＜150 | Phosphate concentrations in pool water are generally maintained below 150 ppb, and once it exceeds 500 ppb, steps should be taken to reduce levels. When chlorine levels are low and phosphate levels high, algae grow rapidly in the pool, causing the water to turn green.
