Does the "shower water" in a fish tank refer to the height of the fish tank or the height of the water level in the fish tank?

Online information is for reference.

The so-called shower head water means that there is water at a position higher than the head.

Feng Shui believes that the highest water level of the fish tank is higher than the position of the head.

That is It will make you wet your head.

Sitting in this position for a long time can make people sick, causing headaches or urinary system diseases. When raising fish, you must pay attention to the following principles:

Don’t commit the crime of "mediting water" or "shower water", which means that the water level in the fish tank is higher than the height of a normal person (more than 190cm). This will make the family's fortune unable to change and be suppressed.

You can’t commit the act of “cutting your feet”, that is, placing the fish tank directly on the ground without raising it; this arrangement will prevent noble people from coming to the door, but will cause bad luck in wealth.
