Go with the flow
The use of water is commonly misunderstood by readers of fung shui books. For instance, having a fountain at the entrance to a home does not automatically confer wealth. Similarly, placing one to the right of the entrance as you look out does not mean your spouse will indulge in extra-marital affairs.
Rather, it is the sector it is placed in (relative to the centre of your home) that determines a water feature's effect. In the productive cycle, water produces wood. Hence, placing it in the romance sectors associated with wood and water energies will increase the likelihood of romantic developments.
Placing it in a sector that contains your home's wealth energy will also increase your earning potential. This may or may not correspond to the position of the main entrance to your home.
You do not need to keep a water feature flowing all day. Leaving it on for a few hours when someone is at home will suffice. However, the feature should always be in operating order and should not run dry. Ensure the water does not become stagnant and become a breeding ground for mosquitoes and other insects.
For those not keen on having a water feature in their home, colours that represent the element, such as black and blue, can be incorporated into the interior design instead.
