Does my fish pond affect Feng Shui?

According to what you said, I think there are two problems that you should pay attention to:

1. Generally speaking, the north is not suitable to be a kitchen, because it belongs to water in geomantic terms, and it is suspected that the kitchen is in conflict with fire and water.

2. According to the theory of connecting Yin and Yang with Feng Shui, it is more appropriate to put the fish pond in the southeast, but not in the east.

Note: The above is only a preliminary analysis based on the principle of geomantic omen, and the specific layout scheme needs to be tested by professionals on the spot.
