Temperature (°C/°F)

Temperature affects conductivity and biological safety in aquariums and hydroponics. Stable readings help prevent stress to plants and aquatic life.

Approximate guidelines:

• Drinking water: Best between 5°C–20°C
• Tropical aquariums: 24°C–28°C
• Hydroponics: 18°C–24°C

Lower TDS and EC values are generally preferred for drinking water, while controlled higher EC ranges may benefit hydroponics and some aquaculture systems. Ordre yours today!
