Do Test Strips Expire?
You already know that you should test your hot tub water regularly. But did you know that your test kits/strips have a shelf life of approximately 1 year? Test strips often have a €œbest before€ date printed on them. If you are unsure if your test kit is still testing accurately bring in a sample of water and your test kit for our water care experts to compare to our in store Photometer Water Lab.
