What is a penis rash? There are multiple conditions that can cause a rash on the penis or in the groin. Rashes are commonly itchy and can be caused by something as simple as an irritation to certain soaps or something as complex as an infection caused by fungus, an STD or pubic lice.
Purple on the fixtures and fittings and plaster = very high chlorine stabilizer or conditioner levels. It can also be caused by metals and/or minerals in the water, particularâ¦ly manganese. The manganese reacts to the high level of chlorine (when you shock your pool for example) and turns the water purple.
Pool Stains & staining caused by metals. Colored water. MOST, but not all, staining on pool surfaces is preventable. The problem is most people dont realize they have metals in their water. Even trace amounts of these metals (iron, copper, manganese, cobalt, silver) can cause staining. In fact theres enough copper in ONE penny to completely stain an average sized swimming pool! Obviously, the conditions have to be right.
