poolrxspa Unit 100-400 gallons Unit

This product works great for our fountain. The summers really heat up a tiny body of water like a fountain, which of course creates the perfect breeding ground for algae. Now we have a clean clear fountain! It’s been doing a great job for months now, definitely will buy again. No longer need chlorine, I love that!

Keeps the spa clean and clear! Have not had to use extra chemicals!

Seems to be working

Amazing mineral product will solve your spa or above ground pool problems! It's a miracle and I use almost no chlorine.

Wow! In 24 hours my hot tub went from swamp water to crystal clear with this! I am shocked!

You really need to go to the website and read the full instructions because the instructions On the package are woefully inadequate.Be sure that you run the pump for 4 to 5 hours to completely dissolve otherwise you get this weird blue foam film, oily stuff on the top of your hot tub. On the website, it shows that if you have any algae in your water, it will be clearing 24 to 48 hours. Maybe it says 24 to 72 either way it’s been a week. The water itself is crystal clear but it still has a bit of a green tint to it. So it has not completely done what it says it will do on the website. Do I think it’s helping overall: yes. Do I think it’s delivering what was promised on the Website: I do not.

Easy to use especially when you will be away for several weeks. It will turn your filters blue but I didn’t notice any problems with it’s use

This product keeps the spa clear and free of algae.
