Winter Care for Swimming Pool Testing Reagents

Storage And Temperature
According to Taylor Technologies, Using aged, or deteriorated swimming pool testing reagents will result in inaccurate test results. Pool testing reagents are perishables, and should be treated as such. Extreme temperatures, too hot, too cold are not good for any perishables and your pool test kit reagents are no exception. Here are a few tips.
  • Keep reagents out of direct sunlight.
  • Store at 38º to 85º Fahrenheit
  • Make sure all bottle tops are secured tightly
  • Keep all reagents in the test kit case
Shelf Life Of Swimming Pool Testing Reagents
“How long is the shelf life on my test reagents” is one of the most common questions we hear. There really is no definite answer to that question. Some test kit reagents have an unlimited shelf life. Others need to be discarded after a certain amount of time. Securing the caps on your testing reagents and keeping them away from other swimming pool chemicals will prolong the life of your testing reagents. Here are a few tips…
·        Indicators have a shorter shelf life than other reagents
·        Reducing agents and oxidizers usually have shorter shelf lives.
·        Acids and Bases are usually the longest lasting of all pool test kit reagents.
·        Test strips, and “Pads” must be used by the expiration date printed on the package.
Frozen Test Kit Reagents?
In certain parts of the country, swimming pool test reagents will freeze. Here are some helpful tips.
  • If the reagents have frozen to the point that the liquid has been pushed from the bottle, discard the testing reagent
  • Do not warm the reagents to thaw. Allow to thaw at room temperature
  • If the reagents have thawed, and there are suspended particles or solids visible, then discard the test reagents.
