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.

A new standard for keeping your Hot Tub water crystal clear – continuously.

Working as much as I do I don't have time to be constantly battling my hot tub. I installed the Frog Ease system 1 month ago and I am amazed on how well this works. Due to my paranoia I was still checking this thing about every 3 days and I haven't had to add a single chemical to the tub. My water is crystal clear and doesn't stink. I'm sold, form here on out.

Frog system for Sundance spas, Sundance 880 modles are supposed to have an adapter to raise the gray holder to allow enough water mover between filters and cartridges. It's supposed to come with the spa, and mine didn't, can't get any help from Sundance as they have horrible customer service, and Frog says I have to buy it from Sundance. Maybe Frog should redesign this for the 880s or help with getting this Piece. I like the Frog system but this has been a hassle.
