pH
Keeping your aquarium pH stable and in optimal ranges reduces stress on your fish, helping them resist disease and tolerate other stressors.
Salinity
Monitoring the salinity of artificial seawater is crucial so as not to create saltwater with an improper salinity level, as it could stress marine life.
Temperature
Aquarium temperature is often the first thing many aquarium owners test for as it is critical for maintaining healthy metabolic functions in fish.
