Unsightly Stains Are Appearing In Your Swimming Pool – But What’s Causing Them?

[Liz Seyi]

While the appearance of your swimming pool won’t be the sole and definitive factor in your pool ownership experience, if staining is becoming visible in yours, this can be off-putting to potential users. It could also, of course, be an indicator of more serious issues that need to be addressed. After all, it tends to be imbalanced water that most often causes staining in a pool.
One thing is for sure – a pool liner does not become stained for no reason. An outside agent of some kind will be responsible for the eyesore stains you might be seeing in your pool.
This shouldn’t be greatly surprising, given the huge variety of substances and materials that inevitably find their way into pool water – encompassing the likes of vegetation, insects, suncream, cosmetic products, airborne pollutants, and more.
All manner of things can be dropped, blown, or tipped into a swimming pool, potentially leading to staining. There are, however, two broad categories of pool stains: metal stains and organic stains.

A quick introduction to organic swimming pool stains

We’ll begin our rundown with organic pool stains, as these are easy enough to explain. When natural elements such as leaves, mud, berries, and algae get into a pool, and are left for too long on pool walls or floors, they can become stains.
Organic stains tend to be in “organic” colours such as green, brown, or yellow, although algae-related staining can be green or black.
Fortunately, organic stains aren’t usually a great threat to the integrity of a swimming pool, and they’re a lot easier to remove than metal stains.
You can test whether a given stain is organic or metal by adding a few sprinkles of granular chlorine to it, followed by using a brush to scrub the granules into the stain. You’ll know the stain is organic if it vanishes. Otherwise, it might be a metal stain.
So, what is distinctive about metal staining in a swimming pool?

The first clue that a particular stain in your pool might be a metal one, is if it is relatively dark and reddish-brown in appearance. Again, though, there are various other hues that metal stains can have, including green, blue, or black.
Such metals as iron, copper, nickel, and manganese can all potentially be responsible for staining in a swimming pool, with iron and copper stains being the most common. The addition of chlorine to pool water can lead to the appearance of these chemically induced spots.
Another frequent cause of metal staining in a swimming pool, is the corrosion of pool fixtures or metal objects in the structure.
