Works great to sanitize my hot tub!

I did a lot of research before I gave these a shot. We have a smaller spa, and I was concerned that I couldn’t be able to use these with the unique filter system we have but we were easily able to install them. All I can say is WOW our water is sooo crystal clear now. We empty and refill our spa every 90 days or so because we use it often but the water has never stayed this clear for so long. Also not sure if this is related but the pool chemistry is more balanced and I have to use less chemicals to balance it. I love this because one of the reasons I went to mineral sticks was so we could use less chemicals. Stock up. These are well worth the price and they are a great deal for what they will do for your spa. My local dealer wanted $50 for ONE stick. So glad we tried these.

These SPA mineral sticks do a great job keeping my hot tub water crystal clear and help spa chemicals last much longer. The quality feels solid, and each stick lasts for months as advertised. The only downside is that they’re a bit tricky to secure in the filter — it takes some patience to get them to stay while screwing the filter back in. Still, overall a very effective product that’s worth using.

I have been using this type of mineral sanitizer in my spa for years since it was recommended by a serviceman. It helps keep the water clear and reduces the need for chemicals in the water. I mark it on my calendar on my phone to replace it every four months and reorder when I use the second one.
