another way is to put the fish tank in the porch position, which is used as a screen and has ornamental value, and it can also make the gas field of the entrance come from twists and turns, and it can kill two birds with one stone.
the third method is that you choose the brightest place in a room to put the fish tank, so that you can achieve indoor gas field balance. If you put the fish tank according to the first and second methods, but the light is too dim, you will still not be lucky, not only will you not make a fortune, but you will also get sick. Therefore, if your fish tank has been placed in a place with poor light, you'd better set up a few small ever-burning lamps, so that it can be improved.
