What causes brown stains in pools?

Sep 29, 2020 | Uncategorized

Having your own backyard pool provides a great escape from the hot and humid Texas days. But there are some things that can put a damper on the fun and keep you out of your pool. We are, of course, talking about pool stains. While most pool stains can be removed pretty easily, others take a bit more elbow grease.

Have you recently noticed any brown stains all over the walls or floor of the pool in your DFW home? Huh! How is that even possible? You are always super vigilant about your pool cleaning and maintenance. You should not be seeing any stains, anywhere in your pool.

 

Pool owners often determine how clean their pool is just by “feel.” If the water looks clear and does not smell, they think everything is okay and adding some chlorine now and then would keep the pool sparkling. But pool maintenance is more than just that. It can be pretty complicated and requires the monitoring of a couple of factors. If you are not on top of it all, you can end up with unsightly brown stains in an otherwise clean pool.

In this blog, we will tell you all about the sources of brown pool stains as well as tips and tricks on how to remove them.

What causes brown pool stains?

If you want to get rid of those embarrassing stains in your pool, you must first diagnose the stain type. Pool stains can have many sources – it could be an algae buildup or even just plain dirt. But how do you determine which is the one you are dealing with?

One way to identify the source of the stain is to look at the color of the stain.

If the stain on the walls or floor of the pool is greenish-brown, you might be looking at an organic material present in the pool – perhaps an algae buildup or just some leaves, berries, and other organic debris sitting on the floor of the pool. Organic pool stains are not usually hard to get rid of, but over time, they sink down and begin to decay on your pool’s floor.

If the stains are brown-black, and can be found on the sides of the pool as well, it would indicate a metal issue – most often iron or copper buildup. Metal can be introduced into your pool water from corroded copper pipes in your plumbing system or rusted pool equipment.

How to get rid of brown pool stains?

Organic stains

If you have determined the source of your pool stains to be organic, you can easily deal with the problem by heavily chlorinating (shocking) the water and giving your pool a little TLC with a good scrubbing with a long-handled stiff brush. If the stain is truly organic, a regular dose of shock and scrub should take care of the problem. Check the pool to see if the pool is clean. If the stains are still visible after performing shock chlorination, you will have to repeat the process.

Metallic stains

Shocking has little to no effects on metal stains, which means that metals stains are a bit more difficult to get rid of. Metal responds best to chemicals, so you may want to scrub the metallic stains in your pool with a natural ascorbic acid (Vitamin C) based product. A good rule of thumb is to use half a pound of ascorbic acid per 10,000 gallons of water in the pool. If the stain was caused by metal, the scrubbing would remove or at least lighten the stain. If the stains are still visible, add more ascorbic acid. Repeat this process until the stains are gone.

How to prevent stains in the future?

Pool stains can be ugly and tough to get rid of, so once you have removed them, you will want to keep them from coming back. For that, it is crucial that you stay on top of your pool maintenance. With a little effort, you can keep contaminants from making their mark on your pool — literally.

To keep organic stains out of your pool, do what you can to keep the pool clean. This may involve:

  • Skimming the pool surface to keep leaves, twigs, and other organic debris from sinking to and settling on the bottom of the pool where they can stain;
  • Trimming trees or bushes around the pool; and
  • Investing in a better pool cover or an automatic pool cleaner

Preventing metallic stains from returning involves:

  • Keeping the pool water balanced (especially the alkalinity, pH, and sanitizer levels) using a good water chemical test kit;
  • Maintaining your pool plumbing; and
  • Keeping the pH level in the pool steady.

All of this can go a long way to ensure your pool is beautiful and clean for years to come!

We hope that this blog will help you understand brown pool stains a bit more, so you can perform an effective pool stain removal and keep your pool clean and hygienic.
