I have been studying TCM and recenly got interested in fengshui.  I have red in many books (that a stove should not be close to the  sink, as water will clash with the fire element).  Now, 3 months ago I installed a fish tank in the southern sector of  my living room. About a month ago my whole family had fallen sick  which in TCM is classified as a damp heat imbalance. (My son and I  had got a lot of cough and hot pleghm, my wife got bladder infection  with blood in urine).  Can someone tell me if this just a coincidence, or the setup  (aquarium- water element installed in the southern sector of the  living room-fire elemnt) made us to contract damp heat  Thanks, Slavek
