SPA Mineral Stick, Hot Tub Mineral Stick, Hot Tub Stick, with 4 Months Lifetime Universal for Pool&Hot Tub to Keep Water Clear(Yellow,2PCS)

These sticks fit perfectly inside the filter compartment and help keep the spa water clear. I bought them because they were a good value for the money by comparison.

So far this mineral stick has done Us justice in her hot tub. We just put it in where the filter goes in the hole in the center and we've had less issues with our water. I feel like it had definitely helped keep the water balanced and clean. The water barley ever smells unless we forget our bromine tabs. It was definitely easy to install and its carefree and worry free too. So far its a little money we'll spent and id buy it again.

These work great and so much cheaper than the hot tub supply store.

Works great ,no smelly water ,clean and clear,my hot tub uses a shorter filter so I didn't have to use the extention, would highly recomend,so easy to install

The mineral sticks arrived quickly. They appear to be just like the ones I've used before in my hot tub. I haven't used them yet but I am confident they will work well.
