If you have a hot tub and want to lower chlorine levels, what should you do? Chlorine is the chemical that gives your water its disinfectant properties. It's also harmful to your skin and can cause respiratory problems if it builds up in the air. Luckily, lowering chlorine doesn't mean giving up these benefits! You need to know-how. This blog post will discuss how people commonly use it to decrease their chlorine levels without sacrificing health or sanitation.

Chlorine

Chlorine is a chemical that has been used as an antimicrobial agent for many years.

It was first discovered in the late 19th century, and since then, it's been widely adopted by different industries, including swimming pools, hot tubs, drinking water treatment plants, and much more.

Chlorine became a popular choice because it effectively kills bacteria that cause diseases like typhoid fever or cholera.

Free chlorine and total chlorine

When you get into a hot tub, some of the water may turn into chlorine. There are two different types of chlorine: free and total. Free is active and breaks down quickly, while the total is more stable and can stay in the water for a long time. If you have too much free chlorine in your hot tub, it will make it acidic and might damage your spa shell or other things like equipment or color fading. Total is the sum of free and combined chlorines; some become combined chlorines when there's sweat on people's bodies or dirt on their bathing suits.

Free chlorine is the active form of chlorine that kills bacteria. It's also known as oxidized or available chlorine because it does not stay in this state for long before reacting with other chemicals to become something else, mostly combined chlorines.

A high level of free chlorine means there are many disinfecting agents in your hot tub water, which will lower the pH and produce acidity over time, leading to damage to your spa shell, electronic components, equipment, and color fading.

Total chlorine is the sum of free chlorine and combined chlorines. Suppose your spa water has high levels of total chlorine. In that case, you'll want to shock it with an oxidizing agent such as granular calcium peroxide so that all those yucky things can get converted back into their active state again.

Sometimes when you check the water in your hot tub, you will find that the total chlorine is higher than the free. Some of it had to break down into other forms. The only reason this happens with hot tubs is that there are some organic compounds in sweat, body oils, dirt on swimmers' bodies, or bathing suits.

Chlorine dissipates

Chlorine is a chemical that you put into a hot tub to make it safer. It disappears over time, so you need to add more of it. You should test how much chlorine there is in the hot tub every once in a while because if there isn't enough, then bacteria can grow and make people sick. That isn't good!

Chlorine dissipates over time, so a low level of chlorine is necessary.

You should test chlorine levels regularly to ensure a safe and healthy hot tub environment.

In general, most hot tubs will have enough chlorine to kill harmful bacteria when appropriately used, but it's always good practice to test for this chemical regularly.

Since no one wants nagging health problems from going into their backyard pool or becoming sick after hopping into their beloved new hot tub – especially if they plan to get naked – testing for chlorine presence is critical.

Chlorine side effects

When you get in a hot tub with too much chlorine, some bad things will happen.

You may notice that the water tastes or smells different.

If you have had red eyes after being in a public pool, this could mean that there is too much chlorine in your body.

Finally, if bubbles are coming out of the water, it also means there is probably too much chlorine, and it needs to be fixed before someone gets hurt!

How to lower chlorine in a hot tub

Below you can use methods to lower chlorine in a hot tub.

  1. You could maintain the sanitizer level so as not to have too much or too little when refilling it and do this regularly so as not to keep checking back now and then just because you want a perfect balance between pH level and sanitizer concentration.
  2. If you are using bleach, try using less chlorine and see what happens. It is also possible to use bromine instead of chlorine as a sanitizer, but it can be more expensive.
  3. You could use bromine or ozone instead of chlorine which is good for skin, does not evaporate quickly, does not need much refilling, but might require more equipment than just chemicals like saltwater generators.
  4. Purchase a chlorine ionizer, which uses an electrical current to lower the amount of active chlorine in your hot tub.
  5. You could use a saltwater generator that helps to balance out chemical compounds and save energy.
  6. Adding hydrogen peroxide instead of bleach for weekly cleaning.

Let's have a look at some chlorine alternatives that you may use in a hot tub.

Saltwater

Saltwater is expensive to run. It does not save energy, and installation can be more costly than using chlorine. However, saltwater has many benefits - it is healthy and safe for you and your family without any harsh chemicals. You will also have fewer red eyes after bathing, which can happen if you are prone to a problem like hay fever.

Saltwater is expensive to run, even more so in a hot tub. There are no power savings with saltwater, and the installation price can be higher than traditional chlorine.

However, it has many benefits such as:

Saltwater is a healthy option with no harsh chemicals. The water feels soft and silky to the touch, smells excellent, and isn't harmful to your skin or hair. It's also safe if you have young children who might play in the hot tub after swimming even when you're not using it - without any need for additional chlorine tablets or sticks that can irritate their eyes, noses, and throats.

In addition, saltwater reduces red eyes from bathing, making it ideal for families prone to this condition, such as those suffering from hay fever.

Bromine tablets

Bromine is a natural element that you can find in the earth's crust, oceans, and atmosphere. It takes the place of chlorine to make your spa clean but without irritating fumes. You can put it in your hot tub by using some tablets or pouring it directly into the water.

Bromine is a natural element that you can find in the earth's crust, oceans, and atmosphere.

Because of its lack of reactivity with organic matter, it has replaced chlorine as the preferred, keeping spas clear.

In addition, bromine does not give off irritating fumes like chlorine, so your eyes won't sting when you pour them into the spa, nor will your skin itch after contact if you've added too many granules by mistake.

Additionally, because bromide salts decompose at higher temperatures than chlorides or iodides, there isn't much risk that it'll burn your flesh since you're unlikely to spill it on yourself accidentally.

Hydrogen peroxide

You can use hydrogen peroxide to lower the chlorine in your hot tub instead of using tablets or chlorine. Hydrogen peroxide makes oxygen and water, so there is nothing terrible left behind. It is also suitable for you because it doesn't do anything terrible as chlorine does to your skin and eyes.

Depending on which type your spa is set up to run off, you can use hydrogen peroxide instead of chlorine or bromine tablets.

Hydrogen peroxide breaks down into oxygen and water, leaving no by-products behind. It's also great because it doesn't require any special equipment like chlorine or bromine tablets since all you need is a pump and an air stone (to mix the hydrogen peroxide into the water).

Hydrogen peroxide works even better than chlorine at low concentrations or temperatures. In my opinion, hydrogen peroxide is the best choice if you can afford to use it since it works well at low concentrations, doesn't have any harsh effects on the skin or eyes as chlorine does, and has a longer-lasting residual than bromine.

Conclusion

There are several ways to lower chlorine in a hot tub. You could maintain the sanitizer level not to have too much or too little when refilling it. Do this regularly to keep checking back now and then because you want a perfect balance between pH level and sanitizer concentration. If you are using bleach, try using less chlorine and see what happens. It is also possible to use bromine instead of chlorine as a sanitizer, but it can be more expensive. Purchase a chlorine ionizer, which uses an electrical current to lower the amount of active chlorine in your hot tub. You could use a saltwater generator that helps to balance out chemical compounds and save energy. Adding hydrogen peroxide instead of bleach for weekly cleaning are also possible ways to reduce chlorine levels nicely.
