Step By Step Hot Tub Chemical Maintenance Guide:

It’s just a few steps we have outlined below exactly what chemicals you need and how to add them to your hot tub in the right order.

You should always have your heating and jets turned on and your air valves turned off before adding hot tub chemicals as this helps to circulate the chemicals around the water efficiently.

You should also wait about 30-minutes in between adding each chemical and re-test before adding any more chemicals so you know what to add and how much to add.

Always add small amounts at a time so you don’t overdo it as it’s easier to add more than take it away!

Sanitize Your Hot Tub:

One of the most important parts of hot tub maintenance is using sanitizing chemicals to kill bacteria.

We recommend using chlorine or bromine for your sanitizer needs, Chlorine or bromine are the most common sanitizers used in hot tubs.

Chlorine is one of the most commonly used chemicals for hot tub sanitation and has been used for over 100 years as a disinfectant in both public pools and spas due to its fast-acting nature against bacteria, algae, and viruses.

Bromine is less harsh on skin and eyes than chlorine, It doesn’t smell as strong as chlorine which is beneficial but it can be more expensive to stock.

There are a few differences between chlorine and bromine for hot tubs, some people prefer chlorine and some prefer bromine for different reasons, Both solutions come with their advantages and disadvantages.

Whichever sanitizer you use, Make sure the pH level is maintained between 7.4 and 7.6.

Check The pH Level:

Test Alkaline & PH Levels Regularly To Keep Your Water Clean and Safe!

pH level: The pH level is a measure of how acidic or basic the hot tub water is.

The standard PH scale range is between 0-14

The ideal PH range for hot tubs is between 7.4 and 7.6

If the level is too low (too acidic), it can cause skin irritation, eye irritation, and scale buildup inside the hot tub equipment.

If the pH level is too high (too basic), it can cause scale build-up and cloudy water.

Alkalinity is a measure of how easily the pH changes — in other words, it’s a measure of water stability, when corrected between 7.4 & 7.6 you are good to go.

When alkalinity levels are too low, the water becomes unstable and unable to maintain a consistent pH level,

When the Alkalinity levels are too high, it usually means there’s too much calcium carbonate in your water, which can also cause scaling issues as well as cloudy water. you can control this with a hot tub scale stop solution.

The key to maintaining a healthy hot tub is keeping the water’s chemistry in balance. The secret to keeping your water balanced is to test it regularly, using a quality test kit.

The pH level of your water should be between 7.4 and 7.6, and the ideal alkalinity should be between 100ppm and 150ppm.(parts per million)

Your water’s calcium hardness should stay between 175ppm and 250ppm.

If your pH is too high or low, you can adjust it with a pH increase or decrease.

If your alkalinity is out of balance, you can use an alkalinity increaser or use a sodium bisulfate pH reducer to correct it.

If the pH level is too low, this could mean that there are too many acidic compounds in your hot tub’s water, which can cause corrosion to occur in pipes and copper heat exchangers as calcium levels rise.

Adjust Your Water’s pH Level:

The pH level measures how acidic or basic your water is – in other words, it measures how alkaline (basic) or acidic (low pH) your water is.

To adjust the pH levels in your hot tub, use a pH increaser or decreaser to bring your levels as close as possible to ideal levels (7.4-7.6).

How Often Should You Adjust The Water’s PH level?

Adjust your pH a few times a week depending on how much you use it. A neutral pH level is 7.4 x 7.6, which is ideal for hot tubs.

Adjust Your Water’s Alkaline Level:

Alkalinity acts as a buffer for the pH level in your water and helps keep it from fluctuating wildly up and down during use.

The ideal total alkalinity level is between 100 & 150 ppm (parts per million)

  • You can adjust alkalinity using Alkalinity Total Increaser or Decreaser, depending on the reading you get from your test kit.

How Often Should You Adjust The Water’s Alkaline Level?

  • Adjust your alkalinity once a week. Alkalinity is the measure of all the chemicals in a liquid that can change the pH level, so it’s essential to keep this within the suggested range of 100-150 ppm (parts per million).

Check For Calcium Levels:

Calcium hardness is a measure of how much calcium is dissolved in your hot tub water, High calcium hardness levels are generally caused by hard tap water.

  • Think of calcium deposits as minerals in suspension that end up forming scale on the hot tub equipment and surface if levels raise.

Scale, which can be difficult to remove without harsh chemicals, feels like sandpaper and is the residue left after water evaporates.

Shock Your Hot Tub Weekly:

While the term “shocking” sounds harsh, it’s an important part of keeping your hot tub water safe and clean.

You should use a non-chlorine shock at least once a week if you’re using your tub regularly.

If you are experiencing any water problems such as cloudy water or green water then you will want to use a chlorine shock rather than a non-chlorine to clear the water up.

Shocking the spa helps you maintain healthy sanitizer levels, as well as remove contaminants from the water such as chloramines and bromines.

Shock the water regularly, Shocking is a process of oxidizing contaminants like oils that collect in the water after heavy use or if it’s been a while since you last used the hot tub.

This process also helps kill bacteria that can build up when the filter is not working properly or you haven’t been treating your water with chemicals as often as you should have been.

How Often Should You Shock Your Hot Tub?

How often you want to shock your hot tub solely depends on how often you use it.

  • If you’re using it daily, shocking every week should be sufficient.
  • If you use your hot tub sparingly, shocking once every two weeks is fine.

Benefits of Shocking Your Hot Tub Regularly:

  • Removes organic compounds like body oils and bacteria from the water.
  • Removes chlorine and bromine odors and irritants from the water.
  • Improves the effectiveness of sanitizing products such as chlorine and bromine.
  • Improves the overall appearance and clarity of the water.
  • The result is clearer, cleaner water that’s healthier for you and your family.

Hot Tub Filter Care – What You Need To Do!

Hot tub filters are extremely important when it comes to keeping your water clean. Filters can quickly become clogged if you don’t maintain them every month

Do I Need To Clean My Hot Tub Filters Regularly?

The answer to this question depends on how often you’re using your hot tub. If you use it regularly, then cleaning the filters twice a week or so should be good.

If you don’t use your hot tub as much, cleaning the filters once a month should be adequate.

What Happens If I Don’t Keep Up The Maintenance Of My Filters?

If you don’t clean your hot tub filters regularly, as a result, they will need replacing, they will become clogged with dirt and debris, which will prevent them from doing their job properly.

  • They’re designed to collect debris that needs removing. Period!

If debris is not removed! This can lead to water issues such as cloudy water, a buildup of bacteria and contaminants that can cause unpleasant odors, and algae growth which can damage your hot tub.

How To Care For Your Hot Tub:

Keeping your hot tub clean and well-maintained is one of the best ways to protect your investment and make sure you get many years of enjoyment from it.

Hot Tub Chemical Maintenance Guide

Over time, maintenance needs do change, so you’ll want to keep an eye on things, especially if you’re a new hot tub owner.

It’s a fact that hot tubs need regular care and maintenance to keep them running at peak performance.

Without regular cleaning and sanitizing, your hot tub can become hazardous to your health.

Below are a few key maintenance tips that will help keep your hot tub in tip-top shape:

Daily Hot Tub Chemical Maintenance Guide:

  • For daily hot tub care, always remember to test and balance your water chemistry. You’ll need to test pH, alkalinity, and calcium hardness, and adjust it as necessary with chemical products.
  • Spend about two minutes each day wiping down the surfaces of your hot tub. Use a damp cloth or sponge with a pH-neutral cleaner to remove any dirt or residue from the shell, jets, and controls.
  • Use a spa clarifier once a week to keep your hot tub water and filters sparkling clean and reduce cloudy water and contaminants altogether.

Weekly Hot Tub Chemical Maintenance Guide:

  • Test the water’s chemical balance with test strips weekly using a kit that includes tests for total alkalinity, pH, and calcium hardness, as well as chlorine or bromine levels if you use sanitizers.
  • Make sure your filters are clean by scrubbing them with filter cleaner and rinsing them thoroughly with a hose. If they’re really dirty, soak them in filter cleaner overnight before scrubbing and rinsing.
  • Vacuum out any debris in your hot tub using a hot tub vacuum to help reduce bacteria spreading.
  • Remove the lid for periods of time. This helps to create airflow and keep algae away from your hot tub.

Monthly Hot Tub Chemical Maintenance Guide:

  • Drain and refill the hot tub once a month (or as necessary. This is one of those things that will depend on how often you use it and how many bathers use it regularly)
  • Ensure all jets, drain caps and filters are secure
  • Clean the waterline with a specially formulated cleaner or white vinegar
  • Backwash or change the filter for a new one
  • Refill with water, Add sanitizer as needed (bromine or chlorine)
  • Check that the pH is between 7.4 x 7.6 and adjust where needed (pH Plus or pH Minus)
  • Check that alkalinity is between 100-150 ppm and adjust where needed (Alkalinity Increaser or Alkalinity Reducer)

Salt System Hot Tubs -Hot Tub Chemical Maintenance Guide:

Salt System hot tubs are different and unique and virtually maintenance-free. These hot tubs do not use chlorine or bromine because they have an electronic cell that creates chlorine from salt.

The water does not taste salty, but you will feel a slight residue on your skin when you get out of the hot tub.

  • Salt system hot tubs are easy to care for because there is no need to add chlorine every week or test for chlorine levels.

They only need to be adjusted from time to time depending on how much you use them.

  • Salt systems are great for people who have sensitive skin but can’t afford an ozone system.

You can also get a good night’s sleep while your Salt System works its magic throughout the night.

A Salt System allows you to enjoy your spa without worrying about adding chemicals every day or testing the pH levels of your water several times a week.

So! If you like the slight taste of salt… Then go for a salt hot tub.

What Is A Salt System Water Hot Tub?

  • A saltwater spa is a hot tub that has an onboard salt system. This system converts the salt into free chlorine that sanitizes the water.

It is not a saltwater hot tub, but rather a hot tub with a salt system. These systems are very popular because of their convenience and ease of use but they do come with their pro’s and con’s like most things in life do.

  • Salt systems are completely different than bromine or chlorine used in non-salt spas.
  • With non-salt spas, you need to add chemicals manually as they dissipate over time.
  • With a saltwater system, there is no need to add chlorine every week.
  • The system will keep your water clean and clear while you enjoy your spa!

What Are The Benefits Of A Hot Tub With A Saltwater System?

There are several reasons that people like spas with a saltwater system.

First and foremost they are less maintenance and therefore cheaper to maintain overall. They keep your spa water clear and clean without having to add chemicals manually each week.

Secondly, people report that their eyes don’t get sore and their skin feels softer after being in a saltwater spa compared to traditional spas with added chemicals.

Thirdly, They are much less smelly as no harsh chemicals such as chlorine need to be added.
