Product Description

With over 20 years of experience we developed and patented our AquaCop technology to effectively lower the harsh chemicals used in swimming pools. By listening to our clients about the negative effects of harsh chemicals in their hot tubs, we decided to modify our proven technology for use in high temperature water, such as hot tubs, spas, and personal swim spas. With this in mind, we developed iONRx to effectively treat these applications without the harsh side effects of traditional chemicals. With iONRx you also will enjoy the added benefit of actually using your hot tub versus the need to be a chemist! The feeling you get after soaking in a spa treated with iONRx is fantastic! Not only will you feel better but all of your suits and towels will not have that harsh chemical smell and feel. Finally, over time iONRx will actually save you money! That's right, by lowering all of the other chemicals needed you will save money over time.

Simply put....iONRx is like a hybrid vehicle. Do you still need to use traditional chemical treatment for your spa? Yes, but you should be able to significantly reduce the amount of these chemicals for your spa. There is NO magical single product that can completely treat and maintain your spa. You NEED to do your part, but the good news is iONRx can help you keep your spa looking and feeling great. With over 250,000 units sold isn't iONRx worth a try?

PLEASE NOTE: iONRx is NOT compatible with Bromine or Enzymes. It will turn the spa cloudy. You may use any other product or equipment that your spa may be equipped with.

How do you use iONRx?

Balanced Water

STEP #1 - Balance Water

Is your water balanced for pH & Alkalinity? If not, it should be for any method of treatment you may use. Please refer to our website if you need help with balancing your water. If you are currently using Bromine or Enzymes you will need to start with fresh water. If your water is over two month old we recommend starting with fresh water.

STEP #2 - Add iONRx weekly

Add 4 oz of iONRx for every 100 gallons of your spa. This needs to be done every week for the first 5 to 6 weeks. After this time you can utilize our test kit to see how much iONRx is in the water. Depending on usage you should be able to start cutting back on how much iONRx you need to add to the spa.

STEP #3 - Weekly maintenance

Every week you need to repeat steps 1 & 2. In addition to that you need to still maintain your traditional chemical program. After a few weeks of iONRx treatment you should start seeing the need for these chemicals to go down significantly. Your water should remain in balance much more consistently and the work of treating and maintaining your spa is now being done with the help of iONRx, which will make your job much easier! You may want to lower the residual amounts of chemicals in the spa at this point

This is hands down the best hot tub water treatment option on the market. I waited 6 months to add my review because honestly, I kept waiting to make sure it would work long term. It does!! My father-in-law got a bad rash when he purchased his new Bullfrog hot tub 6 months ago so I spent hours upon hours researching different chemical options. I purchased ionRx for my tub to see how this option would work. We were very impressed from Day 1. Clear and great smelling spa water! After a lot of flack from our local Bullfrog dealer we ended up determining his tub shipped from the Bullfrog factory with a biofilm that had already grown in the waterlines prior to us recieving the new tub (which we later confirmed and returned the tub for a new one). However, we liked the ionRx so much that we stayed using it. Believe me there isn't a hot tub store that I know of that would recommend this option because they would lose tons of money in the other chemicals they sell as no one would by them (ie: shock, bromine, chlorine, natural enzyme, stain and scale, water clarifier..... Have I forgotten any???) pH up and down and Alkalinity up are the only chemicals you need with this option other than the ionRx and chlorine tablets that come as a kit (I recommend ordering the kit on your initial order so you get the floater and chlorine tabs). Our tub looks and smells amazing and I only do the chemicals every Sunday with the ionRx system (I am super picky and OCD about my hot tub water). It's very simple and a great product that anyone with a hot tub should be using. I also use a mineral cartridge that goes in the filter compartment along with a scum bug floating sponge to absorb body oils but those are just additional steps that I take because I'm picky as heck. 😁

I have now used this product for one entire season - absolutely the cleanest our Jacuzzi has ever been! Strongly recommend, especially if you're like me and have tried numerous ways of keeping water clean and failed! My hot tub used to stink and the water was so cloudy you could never see the bottom. Now I have crystal clear water, no smell, no residue. I use a small floating device with a few tiny chlorine tablets in there weekly and add the iONRx once per week. I also bought two filters this year and rotate them every few weeks. But the big difference is the iONRx - this stuff is amazing. I am a customer for life!**UPDATE** I have now purchased this product over 10 times. One purchase, the color looked a little off in the bottle. I used it anyway, but then noticed shortly after that it was not working properly. I wrote to the company and received an IMMEDIATE response, apologizing and explaining that a pallet of product had been damaged in the sun by the shippers. They said they would be sending me a replacement bottle. To my surprise, within a couple days they sent me 2 BOTTLES, not one! THAT my friends is how to keep a customer very happy! I was back again to having the cleanest jacuzzi you could ever want. Excellent product, excellent company, excellent customer service!!!!!

Seems to work decently well in keeping the tub water clean and the heat pump running for the hot tub. I wouldn't recommend this as use as an anal bleaching chemical, however.

I have had my hot tub for 2 years now, and in that time I have never been able to really relax and enjoy a soak. I've tried every single sanitizer solution I could find, including chlorine, bromine, mineral sticks, enzymes, borates, biguanide / peroxide and every single one of those caused my skin to break out in rashes, become super sensitive, itchy, red and really made me hate my hot tub. Even just opening the cover to test the water for 5 seconds would make me break out and itch like crazy from the fumes.I was about to finally give up on it and try to sell my tub, but decided to try IonRx on a whim. I've known about IonRx for a while but figured it wouldnt be any better than Nature2 sticks. Im thrilled to say I was very wrong. Nature2 does lower how much chlorine is needed, but not by any significant amount and there is no real way to test if its working. Its fine as a backup solution for when chlorine dips to 0, but if you leave it for any period of time at 0 it will still cloud up like there isnt anything in the water.With IonRx, my water has stayed sparkly clear for almost 2 months and all I need to add is about 1 tsp of chlorine a day, or per use. In a 450 gallon tub, this is around 1ppm of chlorine and by the time I get in again its decayed to a level that doesnt bother my skin. The really crazy thing is I went on a week long vacation recently, and so I followed the instructions and put in 2 weeks worth of IonRx, and 2 tbsp of chlorine (my normal shock dose, about 10ppm). When I came back I was absolutely blown away that there was still 2-3ppm of chlorine showing on the test strips. Even with Nature2 sticks, putting in several tbsp of chlroine would disappear within 24-48 hours. I was also amazed that the pH levels stayed where they should be.Long story short, I've tried every product out there for sensitive skin in hot tubs, and this is the closest I have gotten to something that is 1) really easy to maintain and 2) cuts down on my skin problems by 80-90%.I thought this stuff was super expensive at $40/gallon but even in a 450 gallon tub that has lasted me almost 2 months, and the copper levels are testing at a high enough level now that I dont need to even add it every week. I've been using so little chlorine that the CYA stabilizer levels wont become a problem until the 6 month mark when I'd change the water anyway.I started with the recommended trichlor floater, but found it really difficult to maintain a low level of chlorine and its also forbidden by the hot tub manufacturer warranty. Dichlor requires a little more daily maintenance but you use so little of it that CYA levels dont become a problem for months.
