Pool Test Strip Comparison: 6/7 Way Test Strips
When we started this blog posting we had hopes of showing a direct comparison of detection levels on Pool Check 6 Way test strips and Aquachek Select 7 Way test strips… but that all fell apart when we could not find a site that listed all of the Aquachek product’s current detection levels. 
We had to make due, instead, with detection ranges for the Aquachek product. Sorry, folks. We tried.
|
Detection Ranges: Total Chlorine | Total Bromine: 0, 0.5, 1, 3, 5, 10 ppm and 0, 1, 6, 10 20 ppm Total Hardness: 0, 50, 120, 200, 400, 1000 ppm Free Chlorine/Bromine: 0, 0.5, 1, 3, 5, 10 ppm and 0, 1, 6, 10 20 ppm Total Alkalinity: 0, 40, 80, 120, 180, 240 ppm pH: 6.0, 6.8, 7.2, 7.6, 8.2, 9.0 Cyanuric Acid: 0, 30-50, 100, 150, 300 ppm 50 Strips per Bottle |
Detection Ranges: Total Chlorine | Total Bromine: 0 to 10 ppm and 0 to 20 ppm Total Hardness: 0 to 1,000 ppm Free Chlorine: 0 to 10 ppm Total Alkalinity: 0 to 240 ppm pH: 6.2 to 8.4 Cyanuric Acid: 0 to 300 ppm 50 Strips per Bottle |
As far as upper and lower detection limits go, it seems as if only one difference exists between the two products:
- Pool Check 6 Way can detect slightly higher and lower pH levels
Aside from that, we have heard that the Pool Check product uses the same indicator for free chlorine detection as SenSafe Free Chlorine Water Check, an EPA Approved product for testing free chlorine levels in drinking water.
