Water is by far the strongest Feng Shui enhancer. It is in the flow of water can you see chi in motion. With water flowing you can control the flow of chi and concentrate on which sector you would truly like to activate. When you have a stairway pointing directly at the front door a water fall feature can interrupt the quick depletion of chi.
Water is compatible with all sectors even in the fire south where it helps the flames find balance. Still water, however, can cure the 5 yellow and 2 black in the flying star chart with the add help of salt. Moving water is good for areas with flying star #1 and #8.
Some find water calming and helps still the mind when planning on the next move. Water is used mostly to create the flow of wealth either through job prospecting or customer attracting. You've probably noticed many restaurants with water features in front of the door for that very reason. We'd recommend adding water features to bring the flow back into your life, thus helping you become more productive.
In flying star feng shui active water can activate the #4 wood element for love and popularity, though it is said it could quickly lead to scandals for married folks. It's that effective, yes. Use it to activate the number #1 water for career or business endeavors, and the #8 facing star since it is this period's center number.
Still water in the other hand can alleviate the raging #9 fire element, drain the #7 violent tendencies, and lessen the #2 and #5's tendency to create sickenss and loss.
