Dear Geomancer, Kindly advise if there's any adverse effect if there's 3 water tanks directly above HDB flat? Am occupying the highest floor - 16th floor and the 3 water tanks span across mainly the Living room, 1 bedroom and part of Master bedroom. Seems quite big in size from the floor plan. Will presume that the3 water tanks are storing clean water. Thanks for your kind assistance! Lene
