Good, safe, chlorination of well water achieved using e-chlor

### ⭐⭐⭐⭐ Great work done by these tablets
*by A***H on 19 January 2024*

It's a great little product, I was skeptical before buying but I have used 8-10 for my 5000 liter underground water tank, works like a charm. The water smells fresh and although there is a very mild smell of chlorine it's nothing that could ruin your experience. Overall would recommend.
