Why did my pool water turn red?
This is actually a very common occurrence and usually indicates that there are minerals (metals) in your pool. The change in color is caused by a chemical reaction that occurs when the chlorine/shock oxidizes the metals in your pool water. Red or brown water can indicate the presence of iron, copper or maganese.
Why does my pool water look dark?
Dark pool water may be caused by high levels of manganese in the fill water. This can cause discoloration of the water to a dark blue, purple or black clear color. Mains water contains extremely low levels of manganese, but it can be a problem in wells and water sources near plants which are processing manganese.
How do you fix purple pool water?
Place half a pound of pH reducer powder in a small white sock and drop it in the colored area for 30 minutes. If there is a big change in color, then the problem is manganese. Raise the water level of your pool until it is above all the stains. Add muriatic acid.
What happens if you put too much chlorine in an above ground pool?
Excess chlorine can alter the pH level of the water in the pool, making it more acidic. The acid levels can cause any of the following symptoms: Irritant dermatitis which is a red skin rash characterized by raised itchy red bumps. Eye irritation and over-dilated blood vessels in the eyes.
Why are my pool walls purple?
The purple staining is caused when the pool water has formed something called copper cyanurate. Copper cyanurate occurs when excessive levels of cyanuric acid combine with non-chelated copper that is present in the water. Copper cyanurate is not easily scraped, scrubbed or removed.
Why is my pool pH purple?
First, high levels of chlorine (greater than 15 ppm) or bromine (greater than 20 ppm) can cause the pH indicator to turn purple, which does not match the pH color scale. If you’re pressed for time, you could add a drop of sodium thiosulfate to neutralize the chlorine.
