Additional Information

The @ease System combines the proven FROG mineral formula for killing bacteria with SmartChlor Technology that maintains a consistently low chlorine level for weeks.

Unlike normal chlorine that is used up when you get in, SmartChlor continues to maintain the same level, which is up to 75%* less than hot tubs using dichlor (standard hot tub chlorine). That’s why we call it self-regulating.  It goes to work when the hot tub needs sanitizing so there are no frustrating yo-yo chlorine levels.  This time-released method is also why less shock is needed to maintain the hot tub.

This technology is so unique it has its own testing method that’s easier than standard test strips.

In 2 seconds, you can know precisely whether your pH, Total Alkalinity and Hardness are balanced, plus whether or not SmartChlor® needs replacing. Simply dip the FROG @ease Test Strip into the water, remove with the pads facing up and shake once to remove the water on the FROG Test Strips. Then hold it up next to the color chart on the back of the bottle to compare colors.

If the SmartChlor color on the strip is darker than the bottle label, the water is fine. If it is lighter it’s time to replace the Smartchlor Cartridge.

This technology is so unique it has its own testing method that’s easier than standard test strips.

    Easy to control water chemistry without having to worry about chlorine levels. I wish you would sell bulk chlorine and refillable cartridges. The cartridge only lasts about 3 weeks and more expensive than I anticipated. Had I known the cost and life of the cartridges I would have chosen a different hot tub and sanitation method.

    • Bryan Wall

    Just got a new spa with the cartridges. Does not last, out in less than 2 weeks. I’m going back to the balancing myself as this is WAY too expensive and the cartridges should be refillable.

    • Bryan Wall

    The bullfrog cartridges do work well with the spa but do not last as long as advertised. On my A7 bullfrog only getting about 2 weeks before the chlorine is out. Wish they were refillable to reduce waste and longevity.

    I have a 2017 Bullfrog X Premier 8 and I have been reading reviews and seeing responses that do not seem to match up. For instance, one response said “Running the filtration cycle too often can also have an effect on this, make sure you have the settings on what your Bullfrog Spa manual recommends.” I was just at the store today and I told them the manufacturing setting is set at F2 (which is two hours twice a day). They said they would not recommend that and to set to either 4 or 6 hour cycles that run twice a day based on how often you use it.The manual itself like you state does not even make a recommendation. Also, you have a system where you put the cartridges inside the plate that goes between the two filters, but my model does not have any space between them so therefore that system will not even stay in because my filters actually touch each other. Must have been a design flaw for that year. That means I can only use the floating ball version. I agree that the cost is very expensive for how much use you get. I have a 486 gallon tub and I was told by the dealer to use setting 2, but setting 3 was for 500 gallons so it seems more appropriate to set it to 3. At 600 gallons their sheet says to set it to 4, but today they recommended I also set it to 4. No consistency here.

    I really like this system, I get about 4 weeks out of a cartridge, which works well at our 2nd house. The price, however, is way too high and they SHOULD HAVE A WAY TO REFILL THE CARTRIDGES. I feel like I’m constantly ordering and paying for large chunks of plastic, rather than the chlorine that I need.

    Just as everyone has said above, these cartridges only last a couple days. We have a brand new spa set up by the company, yet here we are with the same problems everyone else has. Frog, quit blaming the people for not adjusting it properly, it is simply your system not working. I gave two stars instead of one because for that short time, it works great.

    • Wayni Tao

    Love using the FROG system for our Bullfrog hot tub!! It is so easy and I never have to worry about the chorine levels. Balancing our water is also easy.

    Chlorine does not distribute evenly. It seems like the price is extremely high for these.

    • Wayni Tao

    I would not recommend any spa that uses the Frog ease system. It does not work as advertised. It is very expensive to use, does not last long and when you need to buy the mineral cartridge you can’t buy a 3 pack like the smart chlor. You are destroying the environment with all the plastic we throw away. These cartridges should be refillable.

    • Tom Sager

      I’m really sorry to hear of your experience using FROG @ease designed for Bullfrog Spas.

      It was our hope that FROG @ease for Bullfrog Spas would make things easier for you by simplifying the care of your hot tub. After all, hot tubs should be a place to relax, unwind, and enjoy others company. Based on your review it sounds like we fell short of that mark which is unfortunate.

      I personally believe in the product and I’m confident we could make it a success for you. If you would like, please call in to our water care team at 800-222-0169 so we can hopefully help you out more.

    Does not last long. Does not stay in filter adapter and floats away when opening compartment. Needs to be refillable. Why can I not buy the mineral one by itself?
