Ready to Make The Switch? It’s Easy! Here’s How.

Stop Soaking in Toxic Chemicals. There’s a More Natural Way.

Patented two-stage, all-natural, ultra-low chlorine sanitizer system requires 4 oz. of iONRx per 100 gallons along with tap water levels of chlorine for a hassle-free, clear, and clean hot tub. No more allergies, tight skin, red eyes, coughing or sneezing, or rashes. Transform your hot tub into the most enjoyable body of water you’ve ever experienced.

Step One

Prior to Adding iONRX®, you must start with clear, balanced water (pH and alkalinity). If not, drain and refill spa. Once water is balanced, begin iONRx® treatment.

Step Two

Add 4 oz. of iONRx® per 100 gallons directly to spa water every week.

Step Three

Choose which oxidizer you plan on using. An oxidizer is needed in order to keep your water crystal clear. See chart below for appropriate volumes.

It is extremely important that you follow the directions when using iONRx. Our technical support department is available to help you with issues you may be experiencing, but virtually every time we get a call, email, or chat for clients not having success, the solution is simply they did not follow the directions for iONRx. We understand that you may feel that following the directions closely will not make much of a difference, but that is incorrect. The iONRx treatment system is specifically designed to work as directed or you may not have success. So please take that extra bit of time to read and follow the instruction when using iONRx.

Frequently Asked Questions and usage Directions

Bromine is NOT recommended when using iONRx. You may need to refill your hot tub.

Do I need to change my water before starting iONRx®?

Not necessarily. We only recommend changing your water if you haven’t changed the water in your tub/spa in over two months. As water evaporates in your tub it starts to raise the level of dissolved solids that can accumulate over time. These solids are not dangerous, but they make it harder for your chemicals to work properly.

Can I start using iONRx® immediately even though my hot tub is currently running on bromine and/or chlorine?

Yes. Using iONRX® while those chemicals are still present will not cause any problems and they will naturally dissipate out of the water in a short period of time.

Why can’t I use bromine with iONRx®?

To treat a hot tub or spa, you need two types of agents- an antimicrobial agent to kill bacteria and an oxidizer to get rid of contaminants and keep the water looking crystal clear.

Although bromine is chlorine based, it works very differently than chlorine. Chlorine will kill the bacteria and then burn off leaving less chlorine behind. Bromine will kill the bacteria but then remains in the body of water. Something will then need to burn off the bromine that has reacted with contaminants, which is usually a chlorine based shock. This is how the water will get its clarity back when using bromine. When using iONRx®, we eliminate that whole component of using bromine. By maintaining a very low level of chlorine, similar to drinking water, combined with iONRx®, you will have the best of both worlds. A crystal clear and SAFE spa that uses almost 90% less chlorine based products.

Is iONRx® safe to handle? How do I dispense it into my spa?

YES! iONRx® is extremely safe to handle. iONRx® has been lab tested for toxicity to humans. Have you ever heard of Safety Data Sheets (SDS sheets)? The information provided on these sheets is based on independent lab testing that shows how safe any product is. If someone is not willing to show you these sheets do NOT use their product! iONRx® SDS sheets are available on our website. iONRx® has been tested and awarded CAT IV clearance by the EPA, this means that the technology is as safe to handle as water. Dispensing iONRx® is simple, use any clean measuring cup to dispense the liquid. You are able to enter the tub immediately. You can even dispense the liquid with someone in the tub.

Currently my hot tub foams up a great deal. Does iONRx® eliminate that?

There is no way to guarantee your hot tub will never foam up again. The cause of hot tub foam is something called “thickening water”. This could be caused by a number of factors including, too many chemicals in the water, poor quality chemicals, detergents in your clothing causing soap foam, old water that needs to be changed out. Bromine/chlorine at higher levels will cause foaming on occasion as well. iONRx can drastically reduce foaming in a hot tub by significantly lowering the chemicals in the tub.

According to your directions, the product needs be put in every week. What if I am going out of town?

It is recommended to dispense iONRx® and your method of oxidation every week primarily to keep an eye on your spa. You may dispense enough of each product for two to three weeks if needed.

100% Safe!
