      Does it work – hard to tell. I wish there was a refillable option so there wasn’t all this extra plastic going into the landfill. Or that I could buy one that lasted a year instead of quarterly. At least this is better than monthly. Check out spa cuzn for a natural alternative to bromine and no plastic! I’ve made the switch and it’s the most low maintenance spa solution!

      Replaced this in my hot tub the other week, and I think it definitely makes a difference on how the water makes my skin feel when getting out.

      This cartridge makes hot tub maintenance a breeze. Pop it in, and let it do its work for clear clean water. It says to replace every 4 months but mine lasts longer than that. Definitely recommend if you don’t like to have to remember to continually add stain and scale control chemicals into your tub.

      Not much can go wrong with a mineral cartridge and it is just what I expected. The problem is that I ordered it on June 1 as a Prime Member and it did not arrive until today, June 6. Not the delivery speed I was hoping for.

      Arrived as expected and works as expected. Always love the process of getting something ordered and arriving quickly.

      These keep my hot tub cleaner than anything. They last for months.

      We switched from Chlorine to Bromine and this system has been wonderful. The water is nice and clear and we don’t have that awful Chlorine smell. So much better on our skin.

      Cost Effective Great Product. It works well with the bromine cartridges to provide clean clear sanitary water.
