Hello, I have been raising fish for so many years. I have seen aquarists put their fish tanks wherever they are, and some have changed their balconies into fish ponds to raise koi. Generally, they consider the effect of use, and Feng Shui and other factors will not affect it. big. The light in your location is too strong, and the fish tank is prone to algae outbreaks. In summer, the temperature is too high, and some types of fish will die. On the other hand, light can make the color of the fish deeper and more colorful. Good: 1. Direct sunlight will cause green algae to bloom. A tank of green water and a glass of green hair will affect the appearance. 2. The load-bearing capacity of the balcony is smaller than the indoor floor. Large fish tanks are prone to accidents. 3. It is too close to the bedroom and the sound of equipment operation may affect sleep. 4. The temperature in winter and summer is too low or too high, which increases the energy consumption of thermostatic equipment. 5. The temperature difference between day and night is too large, which is detrimental to the health of fish
