How about a bathtub on the balcony?

Hello, I've been raising fish for so many years, and all the fish friends have seen where the fish tank is. Generally, people who change the balcony into a fish pond to raise koi fish consider the use effect, but Feng Shui has little influence. The light where you are is too strong, the fish tank is prone to algae explosion, and the temperature is too high in summer, and some kinds of fish will die; On the other hand, light can make fish darker and brighter. Ok: 1. Direct sunlight will lead to the outbreak of green algae, a jar of green water and a cup of green hair, which will affect the appearance. 2. The balcony bears less load than the indoor floor, and the big fish tank is prone to accidents. 3. Being too close to the bedroom, the sound of equipment operation may affect sleep. 4. Too low or too high temperature in winter and summer will increase the energy consumption of heat preservation equipment. 5. The temperature difference between day and night is too large, which is not good for fish health.
