Dear Gabriela,
Thanks for visiting my website
From what you described, it does not sound like you are in a Period 5 house. If the house you live in has gone through renovations, refurbishment or you've moved in in Period 7 or Period 8, then it should be a Period 7 or 8 chart. If you are activating the wrong stars, that is why you are not seeing the results.
My answers to your questions:
1) If it is true that the prosperous wealth star is stuck in the center, the solution is not to use water. But to activate the Facing Star #5 star.
2) Internal Water is often only used like a stimulator. It does not bring in wealth. If you want true water feng shui, you have to use external water formations. not internal water placements.
3) I think what you meant is a Period 3 house chart. Listen - there is no need to "renew" or "vibrate" the so called dead qi. Firstly, who told you the Qi is dead in the first place? Period 3 ...is just a "name" of a chart. The chart doesn't become 'weak' after its period. All you need to do is utlizie the positive areas according to that chart. that's all.
4). Firstly ...there is a difference between "Water Star" and a "Facing Star". people often confuse the two. Water Star, which is what many western students call , what is actually the FACING Star. The real water star is the Water "formation" outside your house. Facing Star is the flying star number on the top right of your flying star chart.
Secondly Facing Star #9 is erroneously understood as "distant wealth".
ALL the nine facing stars can be helpful to wealth. ALL it depends on, is how you activate the stars to support YOUR BUSINESS or career goals. even a so called negative Star#2 can help with property related endeavors.
Hope this helps point you to the right direction for now. Yes I may be coming to london maybe in October this year. Keep an eye on my website www.masteryacademy.com for the announcement closer to the 3rd quarter of this year.
As to you question regarding which book/course - I would recommend our homestudy program Feng Shui Mastery Module2 . http://www.masteryacademy.com/estore/itemdetail.asp?iid=715
