I built a fish pond on the outdoor balcony. The water is 60 centimeters deep, and I have eight koi fish. Three years later, the fish grew very big. After feeding in the morning, everything is normal.

Landlord, what floor is your home on? How big is the fish pond?

I also want to buy one on the second floor. Platform 1 floor. The balcony is particularly large. I want to get a big fish pond of 5*2 meters. But I'm afraid I can't bear the load. . It will weigh 1-2 tons. Plus cement, people, 2 tons is appropriate. A little scared.
