the water temperature of the fish tank? If you want to raise the water temperature of the fish tank, you can put a heating rod. The heating rod is usually placed horizontally near the bottom of the fish tank, but not close to the fish tank, otherwise it will cause uneven heating of the glass of the fish tank, or even cause the tank to explode. Do not put the heating rod in vertically, because the heating efficiency is relatively low. Of course, not all fish need to be heated, such as goldfish, koi and other water temperature requirements are broader.
