There are 2 types of low-quality water, hard water, and low water temperature.

Although the term “hard water” may seem absurd, it refers to measuring the number of minerals in the water. It has a loose connection to pH levels. Hard water often has a higher pH level and a greater concentration of dissolved minerals. Soft water, on the other hand, denotes a low mineral content and a lower pH level.

When it comes to water change, bettas prefer a level that is between 5 and 20dH. It’s better to stay in the middle of that range for the greatest results and to protect your fish. Your betta’s fins may curl if the water hardness level starts to rise above 20dH. High water hardness levels can stress fish and, in difficult situations, result in mortality, which harms their general health. Using your water parameters carefully to avoid poor water conditions.
