Water features do not benefit everyone and this can be attributed to several factors. Firstly, the layout of an apartment or office is important. The direction in which a property faces and its location play vital roles in fung shui calculations and are used to ascertain the prevalent flows of chi within an environment. Secondly, a water feature has to be proportional to the size of the home or office - bigger does not necessarily mean better and a small feature without much water in circulation will be ineffective in an office that has more than 50 people in it. The prevailing energy in any given environment alters every day. However, for fung shui considerations, it is sufficient to keep in mind annual changes. Finally, bear in mind that water does not necessarily equate to wealth; having a fountain does not mean you will become a millionaire overnight. Moving water creates yang energy, which will stimulate the prevailing energy in the sector in which it is active. Water does not discriminate between positive or negative chi, which is why it is preferable to seek the advice of a fung shui professional when installing a water feature.
