## Customer Reviews

### ⭐⭐⭐⭐⭐ Keeps my hot tub clean.
*by P***Z on December 3, 2024*

Love this product and have used it for several years. Just two adults using the tub and we change this when we change water about every 6 mo. A little chlorine when we use the tub and no worries about water quality in between

### ⭐⭐⭐⭐⭐ This works so well.  Pool RX. for SPA's
*by K***T on March 3, 2021*

Okay..how does this little item work so well? I have tried TONS of different products to try to keep our SPA clean. I have had so many issues. We have Well water with a low Ph and some Iron. My Brother In-Law recommended this..he has one for his pool. His pool is perfect. I am amazed.I have no idea why but this has made our Spa water look great. I have had to tweek a few fills with a chemical but this item has changed everything. So simple too. Thank you.
