Having a hot tub comes with its share of responsibilities and enjoyment. You can relax in a warm bath experience after a long tiring day, and it is an ideal get-together place for hot tub parties.

However, it comes with the responsibility of cleaning it regularly. After all, you would not want to swim in a filthy backyard hot tub, right? Thus you should establish a clear hot tub maintenance routine that involves adding sanitizers like chlorine tablets to make a hot tub clean.

Over the years, hot tub chlorine tablets have become popular for sanitizing inflatable hot tubs and keeping them safe from harmful bacteria. 

This article will discuss how many chlorine tablets are necessary for a hot tub and the tips for using them.

How Do I Know How Much Chlorine To Put In My Hot Tub?

Unfortunately, there isn’t a straightforward answer to this issue; instead, it relies on various variables, including hot tub size, usage, and water flow. After startup, check your hot tub water frequently to see where the levels are at.

But as a general rule of thumb, it is advisable to use 1-3 hot tub chlorine tablets for smaller hot tubs and 3-5 tablets for larger hot tubs. 

Add more hot tub chlorine tablets if the current supply is insufficient, or lessen chlorine if the level is too high. Due to chlorine tablets’ slow dissolving nature, which causes them to respond more slowly than granular chlorine, you might occasionally need to raise levels with chlorine granules or a chlorine shock pot.

Tips On How To Use Chlorine Tablets In A Hot Tub?

Although chlorine tablets are not the typical hot tub sanitizer, they can offer many advantages to your hot tub. Plus, they are pretty convenient to use. 

If you want to go and start using chlorine tablets for your hot tub, here are some tips you can follow.

Use A Floating Chlorine Dispenser

Because chlorine tablets dissolve slowly, they must be put in a floating dispenser, an in-line chlorine feeder, or a skimmer basket. In addition to ensuring that the tablets never come into contact with the tub surface and are out of users’ reach, this maintains proper flow so the tablets can dissolve.

Consider The Size of Chlorine Tablets

Chlorine tablets are available in two standard sizes. A  20g and a 200g huge chlorine pill, each measuring 3 inches in circumference or 1-inch in diameter. The 20g tablets are really for hot tubs and tiny splasher pools, but the larger 200g pills are primarily intended for swimming pools.

Don’t use huge 200g swimming pool tablets in a hot tub due to the water capacity, as they will result in high quantities of chlorine that could harm hot tub components.

Use The Best Chlorine Tablets

Most chlorine tablets will maintain the cleanliness of your hot tub just as effectively. And the reason for that is that most brands employ identical or closely related substances in their goods. Thus, it largely depends on your hot tub’s budget and unique requirements.

In light of this, some particular chlorine pill brands are recommended for use.

  • 3-inch Chlorine tablets, Pool Time Max Blue
  • Pool and spa chlorine pills from Clorox
  • 3-inch chlorine tablets from In The Swim
  • 3-inch Trichlor pills from Swim Best

Avoid Using Too Much Chlorine Tablets

Having too much chlorine is much worse, so you should be mindful of how much you use because you only need a small amount. (refer to the right doe as discussed above).  Chlorine overuse could harm your tub.

It may cause the tub’s floor to discolor and drop the pH, increasing the acidity. Your hot tub pumps and pipes could suffer such serious damage from the acidic liquid that you would have to replace them completely. Additionally, the water might harm your swimming gear and skin.

Check Water Levels

It is always a smart idea to check your water chemistry regularly. Before and after adding chlorine tablets to your hot tub, check if there are any chemical imbalances and make necessary adjustments to keep the water chemistry balanced.

Is It OK To Use Chlorine Tablets In A Hot Tub?

The cheapest way to eliminate bacteria in a hot tub is with cost-effective chlorine tablets. For people who don’t need to use a hot tub frequently, tablets are a smart option because they ensure that chlorine is released gradually over time.

Yes, because chlorine tablets are a slow-dissolving sanitizer, they must be put in a floating dispenser, an in-line chlorine feeder, or a skimmer basket.

How Long Does A Chlorine Tablet Last In A Floater?

To keep a chlorine residual of 1 to 4 parts per million, add one tablet to your pool feeder, floater, or skimmer for every 10,000 gallons of water. You should do this once a week or as often as necessary. You should add two pills to a 20,000-gallon pool water.

What Can You Use In Your Hot Tub Instead Of Chlorine?

Bromine is the best substitute for chlorine, which many think is preferable to chlorine.

Even though chlorine and bromine almost all come from the same reaction sequence, bromine is less corrosive, kinder to the skin, and more effective in hot tubs because of its high temperature. Bromine is available as tablets or granules. However, it is more expensive than chlorine. Unlike chlorine, bromine regenerates when the water in your tub is shocked, so you need less.
