Frog @Ease Water Test Strips
Most test strips are designed to test for chlorine or bromine levels of conventional sanitizing systems. But FROG isn’t a conventional system. Their bacterial-killing minerals cut the need for chlorine or bromine in half. They created FROG Test strips to help you dial in the correct low levels in your pool or hot tub—which can make your chlorine or bromine cartridges last twice as long.
