How to Manage Hot Tub Chemistry

Does the idea of trying to manage hot tub chemistry make your head hurt? Fronheiser Pools’ experts know it is so much simpler than you initially thought. With regular maintenance and monitoring of your hot tub chemistry, you shouldn’t have major problems keeping things under control. It’s as easy as 1, 2, 3!

1. Manage Hot Tub Chemistry by Testing and Balancing Water Two to Three Times a Week

This step should become so routine for you that you can do it in your sleep. Simply use a test strip to see where the chemical levels in your spa are. These strips will let you know what needs to be added to keep your hot tub water crystal clear and safe.

Recommended spa water parameters are as follows:

• pH: 7.2 – 7.8
• Alkalinity: 80- 120 ppm
• Calcium Hardness: 100–200 ppm
• Chlorine: 3-5 ppm
• Bromine: 2-4 ppm

The strips will let you know if the water does not fall within these parameters. Then you simply add the chemical to correct the problem. 

Check your water more frequently if you use your hot tub daily, and you can go further between if you only use it occasionally. 

2. Manage Hot Tub Chemistry by Cleaning the Spa Filters Monthly

Cleaning your spa filter once a month doesn’t need to be an ordeal. You can start by simply spraying it off with a water hose to remove the dirt. Then drop it into a bucket of water and filter cleaner to soak while you check the water chemistry and add chemicals. 

After it is finished soaking, remove it from the bucket and spray it off once again. Replace the filter, and you are done until the next month.

Make a calendar event or reminder on your phone if that helps you keep track of when a month has lapsed. 

Doing this step will keep your filter in good condition, thus helping your hot tub water chemistry to remain in good condition as well.

3. Manage Your Hot Tub Chemistry by Draining and Filling Your Hot Tub Every Three to Four Months 

This step can also be tracked using a calendar app or reminder on your phone. (We know the three- to four-month time frame can be difficult to keep up with.) You will usually be tipped off that it is time to drain and fill by your water becoming more difficult to balance and manage as well.

This step is super simple. You simply drain all the water from your hot tub. While it is empty, take the opportunity to wipe down the inside, especially the water line and around your jets. Don’t forget about cleaning your cover, too. 

Once everything is clean again, fill the hot tub with fresh water. Add your chemicals and balance your hot tub chemistry as usual. Then your hot tub will be good to go. 

Don’t let the “chemistry” term overwhelm you or send you into panicked flashbacks of chemistry class. With these easy-to-follow steps, you will be a hot tub chemistry expert in no time at all.
