This unique FROG @ease test strip couldn't be any easier to use. These strips let you know when your SmartChlor® Cartridge is empty and are made for the FROG @ease Sanitizing System. This means no more need to measure the level of chlorine in your spa! @ease test strips also measure for pH, total alkalinity, and hardness.
These test strips show a single color on the bottle that tells you to replace your cartridge, or lets you know that it's still going strong in your system. Just dip the test strip, shake it, and get an accurate reading in 2 seconds. The color will either indicate one of two colors - telling you to replace your cartridge or letting you know its ok to leave it in for now!
