What causes swimming pool stains?

Stains in your Arizona swimming pool can be a result of a variety of factors. It’s important to know what’s causing stains in your pool, so the best plan of action can be taken to correct the problem. Here are the most common causes of swimming pool stains:

Organic Material

One of the main causes of swimming pool stains come from everyday things that fall into our pools that are not cleaned out in a timely manner. If you are seeing black, brown, or tan colored stains, these are likely a result of leaves, bugs, plants, etc. that have fallen into your pool and haven’t been cleaned out for some time.

If you are seeing some rust colored stains, these can come from metals like iron, copper, and magnesium. While these stains can come from metal objects in your pool (i.e. diving boards, slides, rails), they can also come from the metals found in your pool water as well.


A pretty common stain you’ll see in un-kept pools, are green algae stains. If a swimming pool is not properly serviced, consistently with the right chemicals, there’s a good chance you’ll see algae stains over time.

Low pH or Total Alkalinity Levels

In addition to the organic materials causing swimming pool stains; other types of stains can also be caused by having low pH or total alkalinity levels. The result of having these levels too low can result in scaling and even corrosion. If you want to eliminate those unsightly scaling stains, and keep your heaters, ladders, or pool lights from corroding, you definitely want to keep your pool water balanced.


Yes, technically spills would fall under the organic material category, but because they are such a common cause of swimming pool stains; they get their own distinction. These are very common on pool decks. Spilled coffee, soda, juice, and sun tan oils/lotions are a headache because they also attract dirt which will stick to the stain.

Getting Rid Of Pool Stains

pool cleaningIf you are seeing stains in your pool, there are a couple things you can try. Tile cleaners can be picked up at hardware and pool supply stores, and can help remove scale, dirt, oils and other materials from your pool. You can also try picking up some rust and scale remover to treat these areas that have scale or rust stains. Make sure your pH levels are balanced or this product will not work effectively.

While these products can help to some extent, they can also be ineffective. They are also a pain to use. Using them may even require a pool drain service. To best get rid of pool stains, especially those that are severe in nature, you need a professional.
