pH | 7.0～9.0 | 1 time/day
Conductivity (us/cm) | ＜2600.0 | 1～2 times per shift
Total hardness (expressed as CaCO3) | mg/L | ＜100.0 | 1 time/day
Ca2+ (expressed as CaCO3) | mg/L | ＜59.0 | 1～2 times/day
Mg2+ (expressed as CaCO3) | mg/L | ＜41.0 | 1～2 times/day
Sulfates (expressed as CaCO3) | mg/L | – | 1 time/day
Cl- | mg/L | ＜135.65 | 1 time/day
Zn2+ | mg/L | – | 1 time/day
Turbidity | NTU | ＜20.0 | 1 time/day
Total phosphorus (expressed as PO43-) | mg/L | 4.0～5.5 | 1～2 times/day
Are there any fungal indicators? Bactericidal and algaecidal agents can be applied regularly.
Not bad:victory:
