Our test kits are our greatest tool. But what happens when the tests we rely on don't do what they are supposed to do? Yes, your tests know how to lie! They also know how to have a bit of fun and not react the way you are expecting. Adds a bit more fun to our job, doesn't it?

Well, the fact is our test will always react within the confines of chemistry, even if we don't understand the chemistry. The only way to truly understand your tests is to understand the chemistry that allows them to work. And there again, another thing to learn in water treatment. This is why I always say that you should learn something every day in the water treatment industry!

Today, we are going to talk about understanding our tests better. I have chosen questions from the Scaling UP! mailbag about tests. What happens when our pinks don't turn pink, and our blues don't turn blue? That's what we are talking about today.

"As a professional water treater, you need to know the procedures of your tests."

"It's better to be consistently wrong than to be all over the map."
