Should I Use a Floating Chlorine Dispenser in my Hot Tub?

Floating Chlorine Dispenser in my Hot Tub lg

Chlorine dissolves fast, and remembering to add it as often as you should can be challenging. To make it easier, you may have asked should I use a floating chlorine dispenser in my hot tub?

Here’s what I know from using one:

Floating chlorine dispensers should be used in hot tubs. They are convenient, inexpensive, and low maintenance. Additionally, the chlorine will be dispersed evenly throughout the week. The floaters also work equally well with bromine tablets.

In this article, we’ll look at how to use floating chlorine dispensers, the pros and cons, whether bromine is better, and how many tablets to use. And we’ll talk about the 1 huge downside.

Let’s get to it…

Can you put a chlorine floater in a hot tub? 

You can put a chlorine floater in a hot tub. Chlorine tablets in the floater dissolve gradually and last longer than the chlorine sold as granules. But, it is good to check the tub manual if that form of chlorine is okay for it. It could be too acidic for it, resulting in discoloration and corrosion.

Apart from enabling the slow dissolving of chlorine, the floater also protects the tub’s surface from direct contact with the highly acidic chlorine tablets. 

But, you must check the tub manual or confirm from the manufacturers that chlorine tablets can be used. If that’s not the case, you can also use bromine tablets in the floater.

The dispenser and tablets are a great addition that’ll help with your hot tub maintenance. Which dispenser and tablets are of exceptional quality and that I recommend?

How do you use a floating chlorine dispenser in a hot tub?

Unlock the floating dispenser’s top by slightly twisting it and place the chlorine or bromine tablets at the base. Replace the lid and twist it to lock it tightly. Then, place the dispenser in the tub. As it floats around the tub, slow-dissolving chlorine tablets are gradually dissolved. 

As you can see from what I shared above, it’s super easy to use. There’s nothing complicated here.

But, please check your manual or contact the manufacturer of your hot tub to confirm if you can use chlorine tablets with your tub.

One of the main benefits of using the dispenser is a more consistent chlorine dosing pattern because it’s occurring as the dispenser floats innocently in the tub. In a sense, it’s a labor-saving device.

After all, you’d have had to manually apply chlorine granules now and then.

Chlorine tablets are inexpensive and are probably the most affordable way to get rid of bacteria. 

The “set it and forget” nature of the method is also great. Over time, you’ll have a reasonable measure of the number of chlorine tablets that’d last for a period.

Do you leave the chlorine floater in the hot tub all the time? 

The chlorine floater should be removed when the tub is being used. It is not a good idea to have the chlorine being dispensed when bathers are in the tub. Chlorine is transmuted into an acid, which in high concentration may be harmful.

In any case, the water should be tested before people soak in it.

Chlorine in high doses may alter the pH and alkalinity level. Using a floater does not negate the need to balance the water and do the usual tests.

It’s best to leave the floater in the tub when you know it won’t be used for some time. 

What are the effects of soaking in a tub where the chlorine level is too high? Is it okay?

One should never soak in a tub where the chlorine level is too high. Find out why in a recent article of mine where I explained in some detail…

How often should I put chlorine tablets in my hot tub’s floater?

Add 3-5 tablets once a week. About 1- 3 tablets for small tubs, or 3- 5 tablets for big tubs. But depending on how many people use it and how often it is used, more may be necessary.

You’ll also test the chlorine levels to know if there’s a need to add more tablets, more granules, or to oxidize the water.

What’s right for each tub owner would vary. Factors such as how frequently the tub is used and by how many, the tub’s size, and water flow play a role.

So, there’s a need to check if the chlorine level is okay, too low, or too high. Proper adjustments should be made accordingly.

A few weeks into using the dispenser and tablets, you’d have a feel for how often the tablets need to be added.  

Assuming you were busy and couldn’t be on top of the tub maintenance, what happens if your chlorine level is too low?

I explored the theme in a recent article of mine. In it, I explained that when chlorine or bromine levels are too low, it can allow bacteria and other harmful contaminants to grow in the tub, making it unsafe for users.

How long does it take for chlorine tablets to dissolve?

As a general rule, 4 to 6 one-inch chlorine tablets will, on average, dissolve slowly over a period of 5-7 days. 

It is vital to note how long the first batch you applied took to serve as an estimate for future reference. The rate of dissolution is affected by some factors.

Water temperature, how often the tub is used, and water flow affect how long it takes to dissolve the chlorine tablets.

Chlorine is sensitive to heat, so if the hot tub water is very hot, the tablets will dissolve faster. Whether the tub is under some shade or it is exposed is also a factor.

If the tub is used sparingly, it is understandable that the tablets would last longer than if they were being used heavily. But relative to chlorine granules, they are slow-dissolving and might be a better option.

Now and then, even when you’ve been on top of your tub maintenance, you still need to shock the water. 

How often should you shock the water? In a recent article of mine, I explained why and how often you have to shock the water. I also compared using chlorine or non-chlorine shock.
