How long will the supplies in my testkit last?

The answer depends on how often you use your kit! While our official schedule involves testing once per month, some of our testers decide to go out weekly. If you are going to test during our official testing weekends, the Freshwater and Compact kits will last well over a year. If you are going out to test more frequently, we recommend that you use some of the more expensive tests less often, such as the dissolved oxygen kit.
