KEEPING TORTOISE POND CLEAN FOR GOOD FENG SHUI

The three tortoises in the pond above belong to my mum.  She started rearing them on the advice of my godmother who said that keeping the tortoises in the north sector of my house would bring her good health.  As her health hadn't been good for the past two months, the pond had been neglected.  When I went back home on Saturday night, I saw that the water was murky and also smelly.  It took me about half an hour to drain the water and then scrub the pond clean.
Not only was the dirty and smelly tortoise pond a health hazard, it was also bad feng shui.  No wonder my mum's health was threatened.
