You can think of hydrogen sulfide like a moody teenager. It reacts dramatically to chemicals, especially chlorine or bleach. When you add chlorine to your water, it oxidizes the hydrogen sulfide, turning it into harmless sulfur particles that you can filter out.
It’s like spraying a stink bomb with a neutralizing spray—poof, the smell disappears. The downside? You’ll need a carbon filter afterward to catch the leftover sulfur flakes.
