Iron in hot tub water can cause staining, discoloration, and can even affect the performance of your hot tub. Here are some ways to remove iron from hot tub water:

- Install an iron filter: An iron filter is designed specifically to remove iron from hot tub water. Install the filter in line with your hot tub’s plumbing and allow the water to circulate through it.
- Use an oxidation process: An oxidation process uses chlorine or hydrogen peroxide to break down iron and other contaminants in your hot tub water. Simply add the appropriate oxidizing agent to your hot tub and allow it to circulate for a few hours.
- Drain and refill the hot tub: If you have a high level of iron in your hot tub water, you may need to drain and refill the hot tub to completely remove the iron. Make sure to properly sanitize the hot tub before refilling it with clean water.

What is the Brown Stuff in my Hot Tub?
The brown stuff in your hot tub might be scum. When looking to remove scum, you should know its cause. Besides the brown scum, your hot tub may also have green and blue-green scum.
Each of these scum types has its cause, and battling the scum means getting the right remover. But you will only choose a suitable remover after knowing the cause of the scum. Brown scum will form when the water’s pH level is too high. And this causes iron in the water to react with the chlorine.
The reaction will create a nasty brown scum that will float at the water’s surface. The scum may also stick on the walls of your hot tub. And that’s what the brown stuff on your hot tub is all about.
How do you Get Stains out of a Hot Tub?
A stain remover comes in handy when looking to remove nasty stains that reduce the glimmer of your hot tub. Most stain removers need a soft rag for wiping off the stains. So, be sure to choose a soft rag. An abrasive rag will only scratch your hot tub’s smooth glimmering surface, which may damage the glossy finish.
Your starting point will be switching off the power supply to the hot spa. Then draining the water becomes the next step. You can then wipe off the stained parts to restore the glossy finish for a brand-new look!
But wiping off the stains is useless if you don’t take measures to prevent stain formation again. Be sure to maintain proper water chemistry to avert scum formation on the hot tub. Make sure the pH level of the hot tub water is balanced after adding sanitizers and other chemicals.

Can Well Water Stain my Spa?
Yes, water from a well might stain your spa. Iron is one of the metals in well water. When it reacts with chlorine, it creates a brown scum that will spoil the walls of your hot spa. Iron also increases the water’s pH value, thus causing your hot spa to have stains.
You can always use a product that balances the water’s pH value to prevent stain formation on your hot spa. But on the positive side, well water is natural and has no additives. Therefore, it is safer than your household water supply.

Is Well Water Hard to Balance in Spas?
While well water is naturally pure and has no chemicals added to it, you can be sure to find plenty of iron and other metal deposits in the water. Dirt may also be lurking in the water. All these impurities can stain the high-gloss surface of your hot spa.
The impurities also make it very challenging to balance the pH level of your hot tub’s water. Yes, well water has high iron content and is very difficult to balance. But with proper balancers, you can excellently balance the pH of your bathwater. And this will prevent the formation of brown scum on the surfaces of the hot spa.
Is it OK to fill a hot tub with well water?
It is absolutely okay to fill your hot spa with well water. But you need to understand a few things. First, well water has iron metal and other minerals such as calcium and magnesium. As such, it is considered “hard.”
There might also be dirt and other impurities, which are not dangerous but definitely annoying. With excellent filtration, your well water will be free of dirt and other contaminants. As a result, your hot spa will be relaxing since the water will not only have the desired temperature but will be clear as well.
Pre-Filtering Well Water While Filling a Hot Tub
When looking to fill your hot tub with well water, be sure to filter the well water. And there are a few ways of doing so. First, connect the well water to your home’s water treatment system before channeling it to a hot tub.
Second, you can use a pre-filter. You can find plenty of pre-filters online on e-commerce platforms. For hot tub owners who like to get their hands-on tools, DIY bucket fillers are an excellent choice!
Pre-filtering the well water ensures dirt and other impurities don’t make it to the hot tub. And this reduces the chance of stain formation on the surfaces of the hot spa. Therefore, it is essential to filter the well water before filling your hot tub with it.
