Calibrating cheap Thermometer + life lesson

Calibrating a Cheap Thermometer + a Life Lesson | Pod Father I thought my tank was at 23.5°C. My hand said otherwise. So I did what any reasonable person does — I made an ice bath, grabbed two thermometers, and spent way longer than I expected learning that I was wrong, then more wrong in the opposite direction, before finally landing somewhere close to the truth. The new thermometer was off by three degrees. The old rusty one was almost perfect. And somewhere in the middle of smashing a block of ice with a hammer in my basement, I learned something that applies well beyond thermometers. When you discover something you trusted was wrong, the instinct is to overcorrect hard in the opposite direction. But overcorrecting is just being wrong with more confidence. It's not until you slow down and test things properly that you actually find the truth. Or at least something closer to it. For anyone running a breeding or culture setup where temperature actually matters — watch this before you trust your thermometer.
