Hot Tub Water Chemical Start Up {Step by Step}

Before using this guide, be sure you know the volume in gallons. Your dealer can help you calculate the volume and assist you with all aspects. They can analyze your water, recommend products, and help you with any questions you may have.

BEFORE YOU BEGIN: Clear debris. Replace or clean the filter thoroughly.

Step 1: Balance


1a. Test water balance parameters to insure they are in recommended ranges.

1b. Add chemicals, if necessary, to balance water to appropriate ranges below

  • Total Alkalinity: 50 to 90 ppm
  • Calcium Hardness: 100 to 400 ppm
Step 2: Prep


2a. Add 10 milliliters of PristineCheck per 100 gallons of water. Circulate 2-4 hours.

2b. Shock with 5 milliliters of PristineExtra2 per 100 gallons of water. Circulate 2-4 hours.


2a. Add 2 ounces of PristineCheck per 1,000 gallons of water. Filter for 6 hours.

2b. Shock with 2 ounces of PristineExtra2per 1,000 gallons of water. Circulate 2-4 hours.

2c. Clean filter thoroughly.

Do You Need To Add Shock After Filling A Hot Tub

You actually dont need to add any spa shock right at this stage. Shock helps kill contaminants and remove compounds that build up over time, like chloramines or bromamines. Because your hot tub is full of fresh water, and you dont have any build-up of contaminants, you dont need to add shock right away.

You can add a non-chlorine shock once a week when your hot tub is in use. This will help refresh your sanitizer levels. You can also use a chlorine shock if youre experiencing issues with your hot tub water, like cloudy water or algae, or if your hot tub is in high use.

Set The Water Temperature

Based on your personal preference, set the water temperature. The recommended hot tub water temperature is between 98 and 102 degrees Fahrenheit. Whatever you set your water temperature to, ensure to keep it consistent. If you reheat the water for every use, you risk stressing the heater and circuit board and increasing your electric bill.

Products To Adjust Ph

The pH levels in your hot tub help control the waters acidity. If the pH levels are low, there is more acid in the hot tub water than if the levels are high. The more acidic the water is, the harder it is for the sanitizers to do their job, causing higher levels of exposure to harmful contaminants.

Low acidic levels are also prone to corrosion build-up on spa components. This can result in an expensive component replacement.

Ensure the pH level in your hot tub stays above 7.4 by using a good balancer or pH increaser. You can also test the water using test strips for an accurate reading to see where your water lies on the pH scale. The test strip will tell you where your water chemistry is according to proper levels.

Chemicals To Put In When Starting Your New Hot Tub

Start Up Kit

Before putting in any kind of chemicals, the first step is to fill your hot tub with water. After filling your tub, you can check for chemical levels. Different hot tubs come in different sizes and brands. The amount of chemicals you will use for the start-up process will vary depending on the size and brand of the tub. You need to know how many gallons of water your hot tub will hold. You can usually find this information in the user manual that comes with the hot tub. The owner manual also has recommendations for how much water to use with the specific chemicals needed to start a hot tub.

After filling your hot tub with water, you will want to adjust your pH level and complete alkalinity. You can purchase tester strips to help you balance the pH level and alkalinity. You simply add the pH increaser or pH decreaser as needed until the tester strip shows the pH level to be between 7.4 and 7.6. Similarly, the alkalinity should be between 100-120 parts per million.

You must balance your pH level before moving onto the next step of the process which is adding a sanitiser to the water. If your pH level is not balanced, the sanitiser might not be effective. When you are adding chemicals to the water, you will want to turn on all of the therapy pumps and spread the chemicals evenly throughout the water.

What Are Hot Tub Chemicals

All hot tubs share one trait: they need regular cleaning. Thats where the chemicals come in.

Hot tub chemicals are mixtures that remove dead skin cells, body oils, and bacteria from your spa water.

They also calm skin irritations and make long soaks more comfortable. And some chemicals ensure your hot tub stays pH balanced, so you dont need to refill it as often.

    Natural Spa Chemicals Mineral Sticks Ozone And Enzymes

    Have you ever wanted a more natural solution instead of the manufactured chlorine and bromine? Then youll be happy to learn natural spa chemicals do exist.

    Your first choice is mineral sticks. This product employs the power of silver and copper ions to keep your water fresh and clean. Moreover, this eco-friendly option also comes with a much more mild smell when compared to the strong odours of chlorine and bromine.

    Sadly, not all is perfect here, so youll want to keep a few things in mind. For starters, mineral sticks lack the sanitation power of chlorine and bromine, so youll want to combine these sticks with a small amount of one or the other to keep your water bacteria free.

    An alternative to mineral sticks is ozone. For the most part, this is another eco-friendly means of keeping your hot tub clean. Only instead of placing a bulky stick in your inflatable hot tub, youll inject the ozone into your water pipe with an ozonator. For products, the Del Ozone Spa Eclipse Dual Voltage works great for inserting ozone in your water.

    Lastly, enzymes work as a great natural sanitizer. These work by targeting oils and destroying them before they are able to grow and pollute your water. Sadly, much like mineral sticks, this product is not strong enough to work on its own. Therefore, you will need to add a small amount of bromine or chlorine as well. One of the best enzymes youll find on the market is the Leisure Time Spa Enzyme.

    Hot Tub Chemicals Basics

    This is the bare minimum that you should know about hot tub maintenance this will save you money and save you from unnecessary hassle.

    The main aspects of hot tub maintenance are associated with water balancing, sanitizing, and oxidizing. These complex terms mean simple things.

    Water balancing. Maintaining correct water balance is an important part of hot tub maintenance. Poorly balanced water causes skin irritation and results in scale build-up and green foamy water. Also, it reduces the sanitizer efficiency, so you end up adding more sanitizer to keep the hot tub free from germs.

    How do I know the water is balanced? Before and after each hot tub use, you should check the water balance with test strips to make sure the water will be comfortable and is safe for the skin. Test strips will show the pH level, total alkalinity, and bromine or chlorine level.

    If you find that the pH level is too high or too low , you should add apH decreaseror pH increaseraccordingly. If you also notice that the total alkalinity level is unsuitable , add a total alkalinity increaserto raise the total alkalinity level and a pH Decreaserto make it lower. Chlorine and bromine levels shouldnt be higher than 3-5.

    Sanitizing . The purpose of a sanitizer is to kill germs in the water. You should add a sanitizer after using the hot tub to purify the water and make it bacteria-free.

    Which Hot Tub Chemicals Do I Need

    The answer to this question about which chemicals do you need or how much of it you need is to test the water first. Make sure that you have testing strips to test the water so that you know how much proportion of chemicals you need to add to level the chemical balance. Once you get a proper reading, you can start adding chemicals until you get the desired chemical level.

    The major chemicals you will most likely need are:

    Clean Out The Jet Lines

    Start Up Kit

    This is an important, but often overlooked step. Before you get to work adding chemicals and balancing your tubs water, you first want to clean out the jet lines from all the algae, bacteria, and other contaminants that have built up over the past few months. To do this, use a product such as Proline Jet Line Cleaner. This will clear out all those nasties so they dont get in the way of balancing the water later on.

    Ph Increaser & Ph Decreaser

    As I have already explained, pH levels need to be controlled and stay somewhere between 7.2 and 7.8. Now its time to clarify what happens if you dont control it all.

    If you let the pH drop too low, the water will be uncomfortable to soak in and you may have irritated skin. Also, acidic water corrodes metals.

    If the pH is too high, the water will also be uncomfortable, but instead of corroding the metals, you may get limescale.

    Adjust Alkalinity And Ph

    Your pH helps your sanitizer work more effectively. And Alkalinity helps prevent fluctuations in pH, so its important to adjust this level first. Alkalinity and pH go hand-in-hand, so adjusting one can affect the other. Thats why its important to add your chemicals one at a time, wait for them to dissolve, then retest your water. And remember, you can always add more, so dont overdo it. Start with a few tablespoons if your levels are only a bit off.

    • Both pH and alkalinity are low: Add alkalinity increaser first. Then test the pH again to see if it needs a pH increaser.
    • Low pH: Add a pH increaser. If your pH is too high, add a pH decreaser.
    • Low alkalinity: Add an alkalinity increaser.
    • Either pH or alkalinity are high: Use pH decreaser to drop them back to the right level.

    And after adding each chemical, let them circulate for at least 20 minutes, then retest your water.
