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.
There are three causes of green pool water. The first is a lack of chlorine. Without chlorine the pool water will quickly start to grow algae and turn green. Water without chlorine, especially if it has an algae bloom, is unsafe to swim in, and can be a breeding ground for mosquitoes and other insects. The second thing that causes pool water to look green (or yellow) is pollen.
