Would love to love this system but our test strips have always shown little or no chlorine. From day one it’s always shown a lighter color indicating my smartclor cartridge is empty which it obviously is not. We have a hottub that holds 400 gallons so I set it on 3 originally. I now have it set on 6 and the color has never changed. The water is clear so I just don’t worry about it but it’s discouraging that it never shows the correct measurement.

I use flippin frog for the 12 ft above ground pool. The color on my strips isn’t the easiest to match after dipping it in the pool because it’s not the exact color of anything shown. When I use other test strips it shows free chlorine at 10 ppm. Is this normal, or are the chlorine levels too high? I have it at the lowest setting.

I love the strips, but I do have a question. I often have where the pH shows Purple. Problem is the ranges are supposed to be from Orange to Red. All my other chemicals check out. Question is. Does Purple mean very low or very high pH???

Are the strips comparable with the app? I’ve not found anything that lines up exactly with the app

I love how easy the test strips are to use. I have one question though. For 4 months, my Bromine level was good. Now all of a sudden, the color on the strip is white. There's not really a white on the color spectrum. There is a yellowish tint and then it gradually gets more purple. Where my reader is white, does that mean too little Bromine or too much?

FAQ’s
In 2 seconds, you can know precisely whether or not your pH, Total Alkalinity and Total Hardness are balanced, or if your Chlorine or Bromine Cartridge /Bac Pac or Torpedo Pac needs replacing. Simply dip the FROG Test Strip into the water, remove with the pads facing up and shake once to remove the water on the FROG Test Strip. Then hold it up next to the color chart on the back of the bottle to compare colors.
