To raise guppies, it is best to install a heating rod. Because guppies are tropical fish, they like to grow in higher water temperature. Most parts of our country cannot be kept in high temperature for a long time, so it is best for breeders to install a heating rod for them. The most suitable water temperature for guppy growth is between 23-28 ℃, and breeders can use heating rods to keep the water temperature in a stable range. Only in a stable water temperature, their growth state and growth rate are the best,

In addition, the heating rod can keep the water temperature constant. When the temperature difference between morning and evening is large in autumn and winter, the breeder can turn on the heating rod to keep the water temperature in a stable range. This can avoid discomfort caused by too large temperature difference.

If you want to choose a suitable heating rod, you should choose it according to the size of the fish tank and the temperature needed by the fish. The first is power. If the water body in the fish tank is large, the breeder should choose a heating rod with large power. The breeder can calculate according to the power of 2 watts per liter of water, preferably higher, so as to keep the water temperature constant. Secondly, there are types of heating rods. Now there are glass heating rods on the market, such as instant heating rods, metal heating rods, ptc heating rods, bimetal heating rods, etc. These heating rods have their own advantages and disadvantages, but ptc heating rods have the highest cost performance.
