Signs you need to use bromine in your hot tub

The first thought that comes to mind before using bromine is, “do I really need it?” Therefore, to facilitate your choice, below we will describe the factors that indicate that you should use bromine.

  1. Not clear water, with dirt and algae. If you have not used chemicals to care for your hot tub, you will definitely see such manifestations of contaminated water. Remember that if you see similar signs in your water, it means that it should be disinfected. This is the first and most important case when you need to start using bromine.
  1. You are not happy with the use of chlorine. Many buyers started using bromine because of their dissatisfaction with chlorine. In particular, bromine has a much less pungent odour and does not irritate the skin and eyes. In addition, bromine works much better in warm water and dissolves much more slowly than chlorine, so it is better to use in the hot tub.
  1. Inability to maintain a stable pH level. Many users who use chemicals to maintain water purity have a problem when their pH levels are unstable. Bromine is the best chemical that can keep a steady and stable level. Thanks to its balanced formula, it can maintain a sufficient level of disinfection without your daily control.

A detailed review of each model

There are so many products, all of the different volumes, different brands, and compositions. We understand how difficult it is for you to decide on the ideal bromine tablets to use. That is why we advise you to pay attention to the detailed description of each product below.

Pros

  • The safest for eyes and skin due to the balanced formula that contains a minimum of irritating chemical elements;
  • The best for saving on chemical costs due to the pre-stabilized tablets which replace the stabilizers;
  • Has a soft and light odour

Cons

Do you have little children whose safety you care about? Or are you tired of the constant irritation of the eyes and skin while enjoying yourself in the hot tub? Then In The Swim Spa Bromine Tablets are perfect for you. Thanks to its unique formula, which does not contain any harmful and irritating substances, you can be sure of the safe use of your hot tub.

One of the main advantages is that the formula is pre-stabilized and will not cause an unpredictable and fast change in pH level (unlike SpaGuard Brominating Tablets, where you need to constantly check the level of bromine in water). This will save you quite a lot of money. In addition, this product makes the water soft and smooth, making your time in the hot tub even more enjoyable.

What is more, these tablets have an almost imperceptible and light odour. But if you are a very picky buyer who does not want to hear even the slightest smell of chemicals, you can buy yourself a Hot Tub Aromatherapy Fragrance Assortment that will make you relax as much as possible.

  • The most cost-effective due to the large and long-lasting container size;
  • Dissolves completely and slowly, maintaining a stable level of chemicals in the water;
  • The widest variety of container size: 10, 25 or 50 pounds

Cons

Tired of spending a lot of money just on chemicals for your hot tub? Forget about it. Thanks to the container weighing 50 pounds, you can forget about buying bromine for the next year. Due to the size and quality of Hydria Clear Bromine Tabs, it is perhaps the best choice for frugal and picky buyers.

Importantly, this is one of the few products that guarantee the complete elimination of algae. This is possible due to the presence in the composition of bromine tablets of special anti-algae elements. However, do not think that this is the only aspect that can please you with the use of these bromine tablets. Unlike Clorox Spa Brominating Tablets, they make the water clean from the first days and keep it in this state all the time long.

However, if you are still unsure of your choice and want to test this product, you can choose a different volume of containers. The manufacturer offers you three options: 10, 25, or 50 pounds.

Due to this, the company is constantly trying to improve its products, and Spa Choice Bromine Tablets are no exception. Thanks to the innovative formula, these tablets last twice as long as others.

Unlike Clorox Spa Brominating Tablets, these tablets do not make the water cloudy and remain solid for a very long time. This means that they will not only save your time but also a lot of money.

How much bromine should I add to my hot tub?

Adding chemicals to water is a very important matter that requires care and responsibility. It will determine not only whether the water will be cleansed of harmful substances, but also whether its will not harm your skin and eyes.

First of all, to find out the level of bromine in your hot tub, you need to measure it using test strips. On average, your hot tub bromine level should always be between 3-5ppm (parts per million). 

The formula for adding bromine
In general, you need to add 0.003 g of bromine per liter. So add 3 g for 1000 litres (the weight of one bromine tablet is 1.5 grams, so you need to add 2 tablets for 1000 l). This formula works in the same way for all hot tub volumes.

Of course when you use tablets, you can’t measure the amount of bromine in grams. But you need these indicators to get a general idea of its normal amount in water.

Also, you need to remember that the pH level must be between 7.2 and 7.6. If the level is lower or higher, you can use a pH increaser (such as SpaChoice pH Increaser) or pH reducer (such as AquaDoc pH Decreaser) to balance the levels.

But also there are other ways to increase or decrease bromine level:

  • If you want to higher the bromine level, in this case, you need to add 3-6 bromine tablets at a time (depending on the size of your hot tub), wait 20 minutes, and then test again. Try to repeat until the level is between 3-5mg/l.
  • If you want to lower the bromine level, you can add a neutralizing chemical, such as sodium thiosulfate. There is no clear amount to add because it all depends on what level of bromine was before. Therefore, start with a small amount, testing the level of bromine every 20-30 minutes.

But if you do not like this option, it is much easier to just drain your hot tub and after re-collecting water add the right amount of bromine.

How to use bromine tablets: a step-by-step guide

You may think: what can be easier than using bromine? Just take the tablet and put it into the water. However, in reality, everything is much more complicated, and if you want bromine to work effectively in your hot tub, make sure you follow all the steps below.

  1. First of all, you need to make a bromide bank. It is needed to have a start point of a bromine level to which you can add bromine tablets to adjust the level of chemicals. It takes 2-3 weeks to create a bromine bank. You can do that by adding kind of chemicals like Spa Choice Bromide Booster Spa Sanitizer each time before you fill your spa with water after drainage. 
  1. After this stage you need to use spa shock (such as SpaGuard Enhanced Shock). It is an important stage because spa shock works with the bromide to convert it to bromine, which will keep your water clear, and clean, kill algae and eliminate any contamination. Remember, that it is preferable to shock the water weekly in order to activate the bromine.
  1. Next, you need to put your tablet in the brominator (it is also often called the “dispenser”). This thing is incredibly useful because it allows the tablet to dissolve evenly and gradually, maintaining the right level of bromine in the water. 

Since most brominators are made for 1-inch tablets, many buyers may have a problem choosing a brand, because often the tablets are a bit larger so they need to buy a new brominator. We advise you to buy SpaGuard Brominating Tablets with 1-inch tablets to be sure that you will not have to spend extra money.

What is a brominator and why it’s worth buying?

Brominator is an important and very useful thing that can not be ignored. It is relatively cheap and will save you a lot of time and money in the future. To describe this thing briefly, the brominator is designed to hold a bromine tablet that will slowly dissolve in water.

But let’s talk about the most important advantage of this thing: if the tablet dissolves slowly, it is ensuring a stable and even level of chemicals in your water. More than once, we have read desperate comments from users that the tablet dissolved in a few days, and the bromine level skyrocketed. In fact, it was easy to avoid this situation just by using a brominator. 

Be careful in this regard and remember that it is better to spend $ 10 on a brominator than five times more on other bromine leveling chemicals.
