Mary Keane –
No more irritation to throat or eyes!!! We have two young kids, so I wanted to avoid treating with chlorine. I found this product and I am impressed. Great product and I’m so thankful that it’s natural chemistry at work!
R. Bostwick –
It’s worth the extra $$$. It got myTub and jets super clean. It did not have a smell at all which I loved since IÕm sensitive to chemical cleaners.
Trevor Smith –
Highly recommend, but you’ll need 2 BAGS A MONTH. A little pricey but is the best thing I’ve ever used in my hot tub. DoesnÕt have a scent and cleans very well.
John Olson –
I put in 45 tablets every day. The chlorine dioxide must be at 3 ppm. I can’t explain how this works but it’s Squeaky clean and I will say I have not seen any scum line. I don’t use any other products any longer.
L. Ann –
It does not have a smell and seemed safe. My two 8 year olds had no issues after I put the tablets in.
Ashley Perez –
we have a intex hot tub. was having to empty and refill every two weeks using our old chemicals. safrax is super easy to use, just throw it in the tablets in the tub and hit the jets. water is crystal clear and no odor, filters seem to last longer also.

This stuff is a little more expensive that most of the other spa maintenance out there, but considering what it’s done for the spa, it’s money well spent! Easy to maintain. I use this daily to keep the water clean. Works great.
Gabriella Toledo –
I cannot believe how SUPER easy it is to maintain a tub with safrax. Just add the tablets every day and it’s perfect ALL the time! It’s crazy! I will forever be using this product!!
DJ Brown –
Expansive but this product is beyond awesome for POOL as my son is allergic to chlorine! I have an 5000 gallons inground pool and for the last 2 years I have not been able to get it clear. It has always been a pretty blue but hazy looking. I’ve tried several clarifiers and flocculants… but nothing worked. That is until I tried safrax! I poured in 10 bags in the evening and the next day the pool was sparkling clean!!! The kids even commented how soft the water feels and no smell. After adding I took my water sample to Leslie pools. My pool was perfect.
Ronnie Gan –
Works good but is quite expensive to use daily. Did a great job of cleaning out the jets.
Sam Soussan –
It works where others havenÕt. This product is amazing. We’ve had a problem getting the tub tubes cleaned for years, we used this product one time and jets got Squeaky clean. ItÕs amazing when you see all of the stuff come out of the jets.
Max Burnett –
Too costly compared to chlorine.
Stephen W. –
Perfect for daily maintenance. This product definitely helps keep the spa water fresher. My water is much softer and actually no smells at all. This product will be part of my spa maintenance.
Pete Anderson –
This will clean your hot tub and leave crystal clear water. This product cleaned up my hot tub so well after it had been closed for a couple of years. It was simple to do, just add tablets. The tub looked clean but the product cleaned out the parts you can’t see, the lines. It is so easy and the water is beautifully clear!
