Q & A
Why Is Water Quality Testing Crucial For Aquariums?
Regular water testing helps maintain a stable and healthy environment, preventing stress, disease, and loss of fish by detecting invisible imbalances.
What Parameters Can Your Testers Detect?
Our water quality testers for aquariums can detect a comprehensive range of parameters including pH, TDS, EC , Salinity, ORP, Dissolved Oxygen, Hydrogen, Specific Gravity, and Temperature.
How Often Should I Test My Aquarium Water?
For new tanks, daily. For established tanks, weekly to bi-weekly is generally recommended, or immediately if fish show signs of stress.
How Do I Calibrate My Aquarium Water Quality Tester?
Calibration usually involves immersing the probe in specific standard solutions (e.g., pH buffers) and adjusting the meter according to the instructions. Calibration frequency varies by parameter.
How Do I Maintain And Store My Aquarium Water Tester?
Rinse probes thoroughly with purified water after each use. Store electrodes in recommended storage solutions to prevent drying out, and keep the device in a cool, dry place.
Why Is Automatic Temperature Compensation (ATC) Important For Aquarium Testers?
ATC automatically adjusts readings to compensate for water temperature variations, ensuring accurate measurements for parameters like pH and EC, which are temperature-dependent.
