pH Level (Acidity/Alkalinity)6.3

Measures water acidity or alkalinity on a scale of 0-14. Neutral is 7. Most fish thrive in 6.5-8.5 range.

Escherichia coli (E. coli) Bacteria77.0 MPN/100mL

Common fecal coliform bacteria indicating possible sewage contamination. EPA recreational limit: <126 MPN/100mL.

Water Temperature8.0 °C

Water temperature directly affects fish metabolism and activity. Optimal range varies by species.

Tp (mg/L) (Water Quality Parameter)0.0

Tp (mg/L) - a water quality measurement. Contact local authorities for specific safety guidelines.

Turbidity (Water Clarity)0.5 NTU

Measures water cloudiness caused by suspended particles. Lower values indicate clearer water. <25 NTU is good.

Water Temperature8.0 °C

Water temperature directly affects fish metabolism and activity. Optimal range varies by species.

Electrical Conductivity17.1 µS/cm

Measures dissolved ions and minerals in water. Indicates salinity and pollution levels. Freshwater: 100-500 µS/cm.

Turbidity (Water Clarity)0.5 NTU

Measures water cloudiness caused by suspended particles. Lower values indicate clearer water. <25 NTU is good.

Escherichia coli (E. coli) Bacteria77.0 MPN/100mL

Conductivity (µS/cm) (Water Quality Parameter)17.1

Conductivity (µS/cm) - a water quality measurement. Contact local authorities for specific safety guidelines.

Specific Conductance (Electrical Conductivity)17.1 µS/cm

Measures dissolved ions and minerals in water. Indicates salinity and pollution levels. Freshwater: 100-500 µS/cm.
