Buying Guide
Choosing the right chlorine for your hot tub can feel tricky. It’s important to get it right. Here are some tips to help you decide.
- Consider Your Skin Sensitivity: Some chlorines are gentler than others. If you have sensitive skin, look for options like BioGuard SoftSpa.
- Think About Usage: How often do you use your hot tub? For frequent use, a consistent sanitizer like Leisure Time Spa 56 might be best. If you only use it occasionally, a budget-friendly option like HTH Spa Sanitizer could work.
