Sanitizing your hot tub is one of the most important steps you can take in hot tub maintenance. Not only does sanitization keep your hot tub free of germs so you can use it safely, it also helps put less strain on the plumbing and other elements of your hot tub. Most people think of chlorine, which is the most effective sanitizer, when they think about sanitizing their hot tubs. There are, however, other options available, such as using Bromine. At Thermospas, you can choose the sanitizer that you prefer and purchase it at a reasonable price. You can purchase these items singularly or as a pack, whichever works best for you!

Simple Conversion Table:
3 Teaspoons = 1 Tablespoon = 0.5 ounce
(The cap on our Spa Activator is equal to 1.5 ounces or 3 Tablespoons)
