Important Questions About How to Raise the pH of Your Aquarium

What Is pH

pH is a measure of how acidic or basic a substance is. The pH scale goes from 0 to 14, with 0 being the most acidic, seven being neutral, and 14 being the most basic. Aquarium water typically has a pH between 6 and 8.

Fish that prefer waters with a high pH are known as "hard water" fish, while those that prefer lower pH levels are known as "soft water" fish. Most freshwater aquarium fish generally do best in waters with a neutral pH of 7.

Why Is It Important To Maintain A Stable pH In Your Aquarium

A fluctuating pH level can be stressful for fish and can even lead to illness or death. A sudden change in pH can also cause problems with the biological filtration in your aquarium, as the beneficial bacteria that help break down waste products are susceptible to environmental changes.

What pH Should Your Aquarium Be?

The ideal pH for your aquarium will depend on the types of fish that you keep. If you have a mixed tank with hard and soft water fish, it's best to aim for a neutral pH of 7. If you have a tank full of one type of fish or the other, you can adjust the pH to suit their needs.

  • Lethargy: If your fish swim less than usual or seem "off," this could be a sign that the pH in their environment is out of balance.
  • Loss of appetite: A sudden decrease in appetite can also be a sign of a pH imbalance.
  • Gasping for air at the water's surface: This is a sign that the oxygen levels in the water are low, which a high pH can cause.
  • Rapid gill movement: Gill tissue is susceptible to changes in pH and can be damaged by sudden shifts. If you notice your fish breathing rapidly, it's a sign that their water is not ideal.
