Water Quality

Updated Mar 18

pH Level (Acidity/Alkalinity)7.9

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

Water Temperature7.3 °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.

Nh3 (mg/L) (Water Quality Parameter)0.0

Nh3 (mg/L) - a water quality measurement. Contact local authorities for specific safety guidelines.

Turbidity (Water Clarity)10.9 NTU

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

Water Temperature7.3 °C

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

Electrical Conductivity647.0 µS/cm

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

Ortho P (mg/L) (Water Quality Parameter)0.0

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

Turbidity (Water Clarity)10.9 NTU

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

Conductivity (µS/cm) (Water Quality Parameter)647.0

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

Specific Conductance (Electrical Conductivity)647.0 µS/cm

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