Hot tub sanitizer with minerals and up to 75% less chlorine*

This hot tub sanitizing system combines proprietary FROG Sanitizing Minerals® with patented SmartChlor® Technology to create Fresh Mineral Water®∞ that’s cleaner, clearer and softer.

Benefits

  • Custom-designed to fit on the filter cartridges in select Jacuzzi Hot Tubs
  • Enjoy softer water, reduced chlorine odors and water that's gentler on your skin
  • Mineral Cartridge lasts 4 months; SmartChlor Cartridge lasts 3-4 weeks
  1. Set the FROG @ease Mineral Cartridge to #7 using the dial on the bottom of the cartridge. No further adjustments are needed for the life of the cartridge.
  2. Set the FROG @ease SmartChlor Cartridge to the setting that matches your hot tub size:
    – 200–350 gallons → Setting 4
    – 350–450 gallons → Setting 5
    – 450–600 gallons → Setting 6
    You can raise or lower the dial later if needed. Once set, it will maintain 0.5–1.0 ppm chlorine as long as pH stays between 7.2 and 7.6, so adjustments are rarely needed.
  3. Remove the filter cover.
  4. If a FROG @ease Holder is already installed, remove it by pulling up and away from the filter cartridge using the top handle.
  5. Open the arms of the holder until they snap into position (the handle with the Jacuzzi® logo marks the top).
  6. Inserting the FROG @ease Mineral Cartridge into the holder: Place the bottom of the rounded edge of the cartridge into the front of the lower opening of the holder and push the cartridge back until it locks into place.
  7. Follow the same procedure with the FROG @ease SmartChlor Cartridge in the upper opening.
    Note: To remove cartridges, tilt away from the holder by pulling at the center top of the cartridge rather than the sides.
  8. Unscrew both hot tub filter cartridges to find the one that does not have a grid underneath it. Once determined, screw both filter cartridges back in place.
  9. Installing the FROG @ease Holder: With the FROG @ease cartridges facing the inside of the hot tub and the handle of the holder at the top, slide the holder down over the filter cartridge that does NOT have the grid underneath it until it covers the entire length of the filter cartridge. If necessary, spread the arms on the holder to get them around the filter cartridge. In order to re-install the filter cover, you must first rotate the holder by pulling the top part out about ½” away from the filter cartridge and turning the holder until it touches the other filter cartridge.
  10. Re-install the filter cover.

Ongoing: Replace the Mineral Cartridge every 4 months (or whenever you drain/refill). Replace the SmartChlor Cartridge when a test strip shows lighter than the “out” indicator on the bottle (roughly 3–4 weeks for an average 400-gallon tub).

Frequently Asked Questions

FROG @ease is an easy, low-maintenance hot tub sanitizing system that helps maintain clean, clear hot tub water with less effort. By combining FROG Sanitizing Minerals with SmartChlor Technology, it creates Fresh Mineral Water∞ that’s Cleaner, Clearer, Softer and Easier® to care for. Unlike standard dichlor hot tub sanitizers, which spike and drop, SmartChlor maintains a consistent low chlorine level of 0.5–1.0 ppm. This self-regulating sanitizer automatically releases chlorine only when needed, making it one of the easiest ways to sanitize a hot tub without constant monitoring. Ideal for anyone looking for a simple hot tub water care solution, FROG @ease reduces chlorine use while helping maintain balanced water and simplifying ongoing hot tub maintenance.

It’s conveniently designed to fit on the filter cartridge in most Jacuzzi Hot Tubs.

No. Use FROG @ease Test Strips only. Standard strips will show misleading readings with SmartChlor Technology.

Hot tubs with 150 to 600 gallons are perfect for FROG @ease.

With standard chemicals, you experience peaks and valleys in your sanitizing routine. When you add chemical, the level spikes. When you use the tub, the level drops. This yo-yo method goes away with FROG @ease because it maintains the same level of sanitizing from day 1 until the day the SmartChlor Cartridge is empty.

SmartChlor is a unique, patented type of chlorine. It will consistently maintain a 0.5 to 1.0 ppm chlorine level as long as the pH is balanced. This would not be enough on its own; but with FROG Sanitizing Minerals, it’s a perfect combination that kills bacteria with minerals and a low level of chlorine that create Cleaner, Clearer, Softer® water.

The blue Mineral Cartridge lasts four months. The silver SmartChlor Cartridge typically lasts 3 – 4 weeks. When the SmartChlor Cartridge is depleted, the FROG @ease Test Strip will be a lighter purple color than the test strip bottle label. That is your cue that it’s time for replacement.

SmartChlor is slightly more expensive than dichlor but less than other systems. SmartChlor offers a nearly hands-off experience that automatically maintains consistent sanitizer levels, saving you time and guesswork while delivering clearer, more comfortable water with minimal effort. And with up to 75% less chlorine*, your suits won’t fade and your hot tub has less wear and tear.

Keeping your hot tub balanced will extend the life of your SmartChlor Cartridge. Keep pH under 7.6. Over circulation could also deplete the cartridge faster.

Fresh Mineral Water∞ is our signature water quality experience — clean, clear and silky-soft water made possible by our patented mineral technology combined with significantly lower levels of chlorine. The result is water that’s gentler on skin and free from the harsh, over-chlorinated feel of traditional hot tub care.

Christina R.

I love using frogease for our Jacuzzi J-475. Maintaining ph and TA is key. We use the spa frequently so we go through smartchlor faster. We use the 6 setting vs 5 bc of our frequent hot tub use. We shock once a week with either maintain or other non chlorine shock. If I need supplemental chlorine bc of a large gathering I use a TBS or more of Jump Start. After a year and a half and some mistakes, the key is to test ph often and sanitizer levels with the strip and we shock once a week. I like having a lower chlorine level due to frogease and the Jacuzzi uv and ozone system.

Christina

As a first time hot tub owner, it took a little trial and error to understand water balancing and how to achieve snd maintain it. Our Jacuzzi dealer gave is a starter pack of frog ease. First three months I diligently tested the water and had trouble with water balancing. Frog ease did make maintenance easy. I unfortunately the chlorine run out and the minerals ran out for us at 3 months. We got swamp water. I purged the biofilm with aaahsome, drained, cleaned and refilled. Did balancing step by step per frogease instructions and now our water is crystal clear again. Even if because of our high frequency of use or size of tub we go through the smartchlor more frequently, I really like the frog ease system and the test strips are accurate. I cross check with a taylor kit on ph. Water balance is key. Our ph is 7.4-7.6, alk is 120, hardness is 150. If the water is not balanced, it will affect any sanitizer you use. I look forward to going away for a week and knowing all will be well. If it’s not, then we’ll figure out why. We are going to keep using frog ease. It works.

Tom Stepanof

I could not find the product I needed for my Jacuzzi, go figure there is a shortage! But I posted a message to King Technologies (Frog) and they sent me 3 dealers that have their products within 1 day. Thank you!

Dana Lucia

Can someone help me find the cartridges near me? I’m going to have to shut down my hot tub, if not. So frustrating! It’s been almost a year since my store has had them and I can’t even find them on Amazon for double or triple the original price, anymore.

Keith Allen

I am having the same problems with finding these filters. Is there an alternative to this set up without having to float a ball in my hot tub?

FROG Products

Hi Keith! We are sorry it has been difficult to find FROG @ease Jacuzzi Cartridges. We understand not wanting to have a floating system in your hot tub. Check out our FROG @ease In-Line System here: https://frog-old.local/product/frog-ease-in-line-system/

Kevin

Tom , go figure same here, brand new tub and no way to balance the water. Disappointed

FROG Products

Hi Kevin! We are sorry to hear that it's been difficult to balance your water. Please call us at 800-222-0169 so we can give you one-on-one advice!

Kevin McIsaac

I am having the same issues with the cartridges that mount to filter. The chemicals never seem to balance. And I agree, the test strips do not seem accurate at all, when i Compare them to the Taylor Test kit system.

Jason

I've actually had a pretty good experience while using these. However, finding them is another story. These have become unobtanium.

Angelique

I have the same system I’m using in my system j355 jacuzzi. Disappointed the chlorinated granular get those clumps stuck in the holes. And usually change within 2-3 weeks due to doesn’t last 4 weeks . ( other chems read within levels just not chlorine ) We only use our hot tub 3-4 times a month but I check it weekly on the chemicals.

Samantha Tillman

This system does not work! Chlorine level is constantly low even at the highest setting with a fresh cartridge. For such an expensive system you would think this wouldn’t be an issue. Disappointing

FROG Products

Hello Samantha! We are sorry about this. Have you been adding a chlorine shock to the water before adding FROG @ease to your Jacuzzi? We recommend this and you can use FROG Jump Start or any other chlorine shock. This is because you need a base level of chlorine in the water for SmartChlor to work with. Please reach out to us at 800-222-0169 or customer.service@kingtechnology.com with any additional questions!

Karen Haycraft

Have been playing with this system for almost 2 years. So far I haven't had to purchase any frog products as I got ALOT free from dealer and manufacture. I have not had a lot of luck and have been supplementing with chlorine granules, sanitizer and floater tablets (when gone for 2 weeks). I have a J365 but have to run on 7 and have noticed that the holes seems clogged regularly. The chlorine levels seem to hold for about a week before the strips are telling me to change my cartridge.
I love the idea of the simplicity of the system but seems to need quite a bit of supplementing to keep water from becoming cloudy & green.
Now I'm to the point of having to purchase products and am wondering if this is the most economical way to maintain my spa.
Would love to have some feedback as to what I may be doing wrong from Frog representative.

FROG Products

Hi Karen! We apologize for any troubles you've experienced. Do you shock your spa monthly? We are wondering if the SmartChlor cartridge is working overtime to keep up with killing bacteria and organic contaminants that should be removed with a monthly shock treatment. We would love to talk to you over the phone. Give us a call at 800-222-0169!

Randall Paulson

I have a the smallest Jacuzzi J-315 and the chlorine and minerals are constantly low. However, the cartridges are never empty but I notice the little holes on the bottom seem clogged. The chlorine setting should be at 3, but I have to put it at 7. This system requires daily monitoring. It’s a new spa but I’m looking for an alternative system. @ease is not easy.

FROG Products

Hi Randall, thanks for reaching out. We're very sorry that FROG @ease has not been a good experience for you so far, and we'd like to help change that. Our customer service team will be reaching out to you shortly with some helpful solutions!
