What is alkaline in fish aquarium?

In fish aquariums, "alkaline" refers to the level of pH in the water. The pH value measures the acidity or basicity of a solution, ranging from 0 to 14. In general, a pH level below 7 is considered acidic, while a pH value above 7 is regarded as alkaline or basic.

Keeping an appropriate pH level is essential for the health and well-being of aquarium fish as different species have specific pH preferences and requirements. Some fish thrive in acidic water conditions, while others prefer slightly alkaline environments.

In aquariums, several factors can affect the pH level, such as the type of substrate, decorations, plants, and the water source. For example, limestone or coral substrates and certain driftwoods can increase the pH level, creating an alkaline environment.

It is important to maintain a stable pH level within the recommended range for the fish species in the aquarium. Sudden or significant fluctuations in pH can stress the fish, making them more susceptible to diseases and compromising their overall health.

Understanding the appropriate pH level for the specific fish species you keep and monitoring it regularly using test kits or pH meters is essential for maintaining a balanced and healthy aquarium environment.
