4 Pack Spa in-Filter Mineral Sticks Parts Cartridge Sticks for Hot Tub Spa Swimming Pool Fish Pond Filter Cartridge, Last for 4 Months (Blue & Yellow)

Performs as hoped for and at a great price. Use in 8•8 ozinated hot tub.

The media could not be loaded. My first hot tub was purchased in 2012. I used miner sticks from the hot tub store because I didn’t want the feel and smell of chlorine. After a couple years I found these and started buying these several years ago instead of the regular mineral stick I was getting from the spa shop.I honestly can not say that the ones I used to get are better. My water stays clear and balanced with no issues.Good product and keeps my hot tub clear and fresh!

Shipping on time. Good product

I have been using these since we purchased our spa in 2020. We have very hard water where we live and the agent /company we purchased the spa recommended we use these to eliminate scale formation on the walls of the tub.I change these every four months and then simply fit them inside the filter. I do use one of the sticks so that I can pull them out of the filter well when I change them out.

Have been using these for 2 years.

I've used both name brand and this off brand. I have now been using the off brand for a few months. I am happy with the results and cannot tell a difference between this and the name brand alternative. These are going in a 2018 Bullfrog. I modify the case to fit.

We use these mineral sticks in our hot tub. This four pack is an awesome deal. Great quality just like the ones we were buying at the pool store but very reasonable.

These tubes were much smaller than I expected. They do not work as well as my other brands.
