Keep reading to learn a few tips that can help you identify stains in your swimming pool so that they can be promptly removed.


Organic Matter Stains

One of the downfalls of many pools is that they’re wedged into existing backyard landscapes. That means that the pool was a later addition that came after the landscape was constructed, which can result in pools that are close in proximity to trees and shrubs. Unfortunately, those beautiful plants and trees can cause stains when their leaves fall into the pool and decompose, as they will leave green or brown stains on your pool surface. Also, stains that are blue, red, or pink can also develop when berries or blooms from surrounding vegetation falls into the pool. An organic stain can usually be removed with the application of chlorine applied directly to the stain. If the stain is truly organic in nature, it will be almost instantly diminished.


Metal Stains

There’s some metal in every pool by design, and there’s also the potential for metal debris to find its way into your pool as well. In the presence of water, metals oxidize, which can result in pool staining issues. For example, if you see a green stain that develops in your pool in the absence of decomposing organic material, it’s probably the result of copper oxidation. Likewise, red, orange, or brown stains are likely to stem from iron or steel that’s oxidized. Sometimes, iron stains can even be green depending on the water conditions and content of the metal. If metal is to blame for your pool stains, you can apply ascorbic acid, also known as vitamin C, directly to the stain.

Manganese Stains

Manganese is an element that can be found in some water supplies, especially when pools are filled using well water rather than water from a local utility. Though it’s usually invisible in water, it does undergo a chemical reaction when exposed to chlorine and nonchlorine shock products used to keep pool water clean and clear. Pool water that’s loaded with manganese will take on a dark, purplish tone once chlorine is added to it, and that can cause significant staining of grouts and other surfaces in the pool. The best way to get rid of manganese stains is through super-chlorination of the pool, which causes the manganese to oxidize more quickly. Then, the resulting rust settles to the bottom where it can be vacuumed out of the pool.
