OK.
Such a grid is 4m by 3m

This fish pond of yours, with an overall volume of cubic meters, weighs 720 kg if it is filled with 90% water. Not a big problem. If you are making a fish tank, place it on the balcony evenly. It doesn't matter if it's built with cement or tiles on the balcony.
One of the key questions is what is the width and height of the fish tank? But I think the fish tank is easy to grow moss in a sunny place, and it is very troublesome to clean up.
After adding water to the stone tank, it is about 750 kilograms, that is, tons, there is no weight, and the balcony has a tie beam, which is still very valerian, and there is no problem in bearing this weight!
