What Is A Hot Tub Sanitizer And Which One Should I Use?

 

Now that you’ve found the perfect spot for your hot tub in your home, it’s time to take care of it! Just like a new car, the better you take care of your hot tub, the longer it will last and the more “miles” you’ll get out of it. Sounds pretty good, right?

 

The biggest aspect of taking care of your hot tub lies in the 300 to 700 gallons+ of water pulsating through your tub. Hot tub sanitizers kill bacteria and purify the water in your hot tub. They are absolutely the most critical component to keeping your hot tub clean and ready for use.

 

The choice for which sanitizer you will want to use and each method comes with its own list of pros and cons, and range in everything from price to time commitment. We’ve rounded up the top types of sanitizers out there to give you a better feel for what the options are and what we recommend for your different needs!

 

Chlorine

 Chlorine is the most commonly used sanitizer for pools, but cannot be used alone for spas, as it isn’t available in tablet form. Not being in tablet form causes the particles to dissolve too quickly. Paired with a mineral sanitizing system, it is a wonderful way to burn off dead organic matter and clear up cloudy water.

 

Using too much chlorine can bleach or damage anything it comes in contact with, including the spa cover to your flowery swim suit.

 

Bromine

 

Bromine is very widely used for hot tub sanitization. It comes in tablet form and is usually inserted into a floating bromine feeder in your hot tub. This method provides a non-stop flow of sanitization to your water system.

 

Chemically, bromine and chlorine are very similar to each other, but how they react in the water is very different; chlorine has a very short life in hot water, while bromine is very stable. Chlorine will need to be added more frequently to your hot tub while bromine will last longer in the water. There are pros and cons to this depending on your preferences. Overall, bromine has been gaining popularity over chlorine because it is not associated to that same chemical smell as in public pools, and it does not irritate the eyes.  Bromine is gentler on skin and will slow dissolve always leaving a residual in the water.

 

Bromine can leave some people’s skin dry or irritated and the smell is different than chlorine. so make sure to test run this method before committing!

 

Mineral Sanitizing system

Marquis® has partnered with Spa Frog®, one of the best manufacturers of natural minerals to help soften and sanitize water. Spa Frog® systems combine minerals and a small amount of bromine to create an optimized sanitary environment.

 

When you combine minerals, the amount of bromine needed is greatly decreased. This is a highly recommended sanitization method, combined with minerals and ozone!

 

Ozonators

 Ozonators are add-on components in hot tubs that produce ozone and disperse this terrific oxidizer through the air lines. Ozone acts as a defensive lineman in your hot tub, and destroys bacteria, skin cells, oils, and other organic matter that may be harboring in your water.

 

Ozone has a very short half-life in water so it may not be your only method for effective sanitization, it must be paired with a chemical, like bromine. Clients that use ozone sometimes notice bleaching of the spa cover liner, but overall love the performance associated with ozonators.

 

Salt Systems

Salt water hot tub systems are a great alternative for sanitization and are identical to any other hot tub, except for a chlorine generator that converts salt to chlorine. A generator will cost you between $200 and $600 initially, and then you’ll only need about $25 a year in salt to maintain the system.

There are many pros to this type of sanitation including less chemical side effects, such as dry skin, irritated eyes or fading of swimsuits and spa covers. You don’t have to buy chlorine and there is a steady flow of chlorine from the salt generator, so there is a reliable level of sanitization. The cons are that Salt water can be harsh on your hot tub components.  Anyone knows that salt is a corrosive, just look at cars near the beach or on the East Coast where Salt is added to the roads during winter. Salt in general can void your warranty, so always check with the manufacturer before installing on your hot tub.  Salt water chlorinators can also over produce, meaning water must be dumped and fresh water added if there is too much chlorine to safely use the hot tub. Salt water can be harsh on your surrounding plant life over time if your spa is outside, and some people don’t like the smell associated with salt in their hot tub.

Overall, make sure to look into any sanitization option closely to make sure it is the right fit for you and your hot tub! Remember, all reusable water must be sanitized to be safe, so read between the lines on any products that claim they are all natural, or contain no chemicals.
