PH Meter for Aquarium

PH Meter for Aquarium

Measuring the pH of your Aquarium with a pH meter is very important because you want the pH level of your water to stay as balanced a possible. Your aquarium fish and your aquarium plants all prefer a certain pH level. If you expose your fish or plants to a pH level that is too far above or below their ideal pH level, you will damage their health and it could lead to death and health issues.

How to measure the pH of Aquarium

You measure the pH level of your aquarium with a calibrated pH meter or pH probe. You can buy our high quality pH meters right here and the pH calibration solution right here. 

What is the ideal pH level for an Aquarium?

It is impossible to give a precise pH level for all fish because fish swim in water with different pH levels around the world. Saltwater fish for example prefer a slightly higher pH and tropical fish prefer a slightly lower pH level. The ideal pH level for your freshwater aquarium is generally between pH 6.8 and pH 7.8 but it could be more or less, depending on the variety. Inside the Aquarium the plants and the fish are producing a constant chemical reaction that has an impact on the pH value of your aquarium.

How often do you measure the pH of your Aquarium?

It is recommended to test the pH level of your aquarium at least 2 times per month. (1 time per month minimum) Do not worry if your pH level is slightly above or below the ideal pH set point for your fish. As long as your fish are behaving normally, you are best to keep the the pH level as it is.
