So you decided to take a chance and acquire the perfect hot tub for you. Now that you’ve finally purchased the hot tub of your imagination and have identified the ideal location for it, you’re looking forward to the day when you can jump right in and relax. But wait a moment! Don’t ignore the most essential feature before you can sit back and enjoy that warm, bubbly water: maintaining optimum water chemistry. Do you have the right spa chemicals at hand? Let’s take a look at the appropriate chemicals needed for hot tub maintenance.

Maintaining the chemistry in your hot tub is similar to maintaining the chemistry in a swimming pool once you comprehend what has to go in (and out of) your hot tub water. Balancing chemical compounds for Absolute Alkalinity, pH regulators, disinfectants, and shock remedies are all part of keeping your hot tub’s chemistry in order. Don’t be scared by this jargon; you don’t need a Ph.D. in chemicals to understand what’s going on within your hot tub. This article will show you how to keep the composition of your hot tub water in good shape! So, what kind of chemicals do you need for your hot tub?

Essential Chemicals Needed For Hot Tub Maintenance

Spa MetalFree

Natural Chemistry 04133 Spa Metal Free, 1-Liter
  • Natural Chemistry spa metal free is a powerful chelating agent
  • Phosphate-free formula prevents staining and water discoloration
  • Deactivates stain causing metal; will not affect water chemistry
  • Compatible with all sanitizers and pool surfaces
  • Comes in 1-liter container

If you’re filling up your hot tub for the first time or closing it, let the water circulate for about an hour before actually applying Spa MetalFree. Regardless of your source of water, this device is quite handy. Metal-Free is the best option because metals are present in most tap and well water sources.

It is essential to handle metals in the water before adding or adjusting any additional chemicals. This simple procedure helps to prevent and control unsightly blemishes on spa and hot tub surfaces. Allow 4-6 hours for the Spa MetalFree to circulate before continuing.

You should test the water at least 2-3 times each week to ensure that your hot tub’s current chemical composition is still within acceptable limits. To collect a water sample, we recommend scooping it up approximately a foot under the surface. Chlorine/Bromine, pH, Total Alkalinity, and Calcium Hardness are some of the most typical chemical components to evaluate using a spa test kit or test strips.

pH and total alkalinity

We’re emphasizing Total Alkalinity and pH since they work together to preserve chemical balance in your spa or hot tub. They usually come in the form of chemical kits. Total alkalinity is the level of alkalinity in your hot tub water that helps to manage and stable the pH. Essentially, pH measures how acidic the water in your hot tub is. Do you find the connection?

When the Total Alkalinity is not within the recommended range, the pH in your water will fluctuate and become volatile. Before treating pH imbalances, consider Total Alkalinity first.

  • Use a Total Alkalinity Reducer if you need to lower Total Alkalinity.
  • Add a Total Alkalinity increase if you need to enhance Total Alkalinity.

When the pH of your hot tub water falls under 7.2, the water becomes corrosive, making it unpleasant to bathe in and potentially damaging portions of your hot tub’s internal system. Scaling, discoloration, and hazy water might emerge when the pH exceeds 7.8. If you use chlorine as a sanitizer, a high pH may diminish its effectiveness.

  • If your pH has to be lowered, use a pH decreaser.
  • Use a pH increase if your pH has to be raised..

When it pertains to chlorine vs. bromine in a spa, there is a lot of contention. These two chemicals are needed for hot tub sanitization. In our expert view, bromine is preferable. This is because it is more heat resistant and may be reactivated with a tiny portion of chlorine or MPS shock, rendering it a more efficient sanitizer over time. Bromine, on the other hand, has the disadvantage of being more expensive than chlorine. Even then, we feel that the expense is justified because bromine is a potent sanitizer that is more resistant to high temperatures and variable pH levels, has a milder odor, and is less prone to cause skin irritation. You’ll require a bromine enhancer if you’re using bromine to raise bromide levels after draining.

Frequently shocking the water in your hot tub is an important component of keeping it in good condition. You should jolt the water when you first open your hot tub, after a period of inactivity, or after heavy use. But how do you make use of this spa chemical? Weekly shock your hot tub with granulated chlorine. Then, whenever you use the hot tub, add a small amount of non-chlorine shock to maintain it clean and clear. It’s simple!

Let’s look at why it’s so important to shock your spa water:

Shock, for instance, destroys germs. Pathogens in your spa water are killed by chlorine and bromine. However, if you don’t use shock treatments regularly, your hot tub will quickly become overtaken with chloramines and bromamines (inactive sanitizer that has combined with impurities in the water), and your sanitizer won’t be able to operate properly to keep the bacteria at bay. Shock increases the levels of available Chlorine or Bromine in your hot tub by degrading inactive sanitizers.

Conclusion

We hope you have learned more about which chemicals are needed for your hot tub from this article. Having the appropriate supplies in hand ensures that your hot tub is ready to use whenever you need it. Rest is essential while using a hot tub, so make the most of it!
