In the process of buying a house and we just had it inspected and the inspector noticed a serious build up of algae in the upper toliet tank area. He thought it might be a sanitation issue. We are curious to know if it is at all fixable or do we need to replace the toliet. Why does algae grow in the toliet and is this a sign of other problems?
alga is a chrorophyll bearing plant widely distributed in fresh and salt water and moist lands. It may have grown from the tank water being dormant, however I would think that would have to be a long time. Also the lack of light required (photosynthesis) was not present in a dark toilet tank. Just to be on the safe side, have a water sample done by a lab. At the same time have the sample checked for lead content in ppm and other trace elements.
