Water treatment is one of the most important aspects of maintaining a pool, hot tub or spa. It’s essential to have properly balanced water that will keep swimmers safe and your equipment running smoothly. However, many people make the mistake of thinking that you can use the same approach for both pools and hot tubs. Below, we’ll discuss how addressing water imbalance in a pool differs from addressing water imbalance in a hot tub.
Understanding the Differences in Chemical Composition
It’s important to note that you shouldn’t be buying the same chemicals for hot tubs, spas, and pools, as they’re simply not interchangeable. While you might find similar things on the ingredients list for both pool and hot tub chemicals, the concentration is different. This is because the chemical composition of the water is different for each one. There are certain aspects that set them apart from one another, and it’s important to understand these differences before you start treating the water.
1. Water Volume
The first and most obvious difference is the amount of water that each one holds. A pool typically contains several thousand gallons of water, whereas a hot tub only contains a couple hundred. This might not seem like a big deal, but it’s actually a crucial difference. The amount of water in each one determines the amount of chemicals that you’ll need to add. For example, let’s say you’re trying to raise the pH level in your pool. In order to do this, you’ll need to add a chemical that contains alkaline. If you have a small hot tub, you might be tempted to use the same amount of alkaline that you would for a pool. However, if you were to add the same amount of alkaline to a hot tub as you would to a pool, you would end up raising the pH level too high. Alternatively, if you use hot tub chemicals for a pool, it would be too diluted and therefore wouldn’t make a difference to the water balance at all. That’s why it’s so important to make sure that you’re using the right amount of chemicals for each one.
2. Temperature and Evaporation
Another big difference between pools and hot tubs is the temperature of the water. Pools are typically kept around 70 to 80 degrees, while hot tubs are usually filled with water that’s around 90 degrees or the low 100s. The higher temperature in a hot tub causes the water to evaporate much more quickly than it would in a pool. This also means that chemical reactions will happen quicker. If you use pool chemicals, which are a lot more concentrated, it will be more difficult to bring the levels back to the ideal range.
One advantage that a hot tub has over a pool though, is that if you make a mistake, you can easily drain the water and simply refill it if there’s an imbalance that is too drastic.
3. The Jet System
Finally, you also have to take the jet system into consideration. A pool’s jets are designed to circulate the water in order to help with filtration. Hot tubs, on the other hand, have jets that are specifically designed to provide massage. These jets are a lot stronger and will cause water to be dispersed much faster. If you put pool chemicals in a hot tub, they will be distributed in a shorter amount of time because there’s less water, which means that issues in chemical imbalance can happen faster, too.
Now that you know the key differences between pools and hot tubs, it should be easier to understand why you can’t use the same water treatment for both. Doing the necessary research on what type of chemicals to buy and how often to add them can save you a lot of money in the long run. You can even ask your local pool or spa dealer for help so you can get expert advice regarding this. At the end of the day, it’s always best to err on the side of caution and use the right chemicals designed for each one. In doing so, you’ll be able to maintain a healthy and balanced swimming environment for everyone to enjoy.
