1. Having never used a kit before, how long can you generally expect a kit like the Taylor K-2006 to last? Do you typically replace reactants individually, or end up buying a whole new kit when needed?
2. Do you usually pour the results of a test back in the pool after doing the test? Can doing this cause any issues?
3. How much do you need to rinse/clean out a bottle or comparator between tests to ensure accurate test results?
