If you've ever had to shock a pool, you'll know that there's a huge range of products on offer and they all have similar-sounding names. There's pool shock, pool chlorine, chlorine tablets, chlorine bleach, liquid chlorine and much, much more.
It can be confusing and more than a little worrying. If you don't know what you're doing with pool chemicals you could easily make your pool dangerous to swim in. That's why I spoke to a pool expert about the differences between these terms and found that they all relate to the same chemical in different forms and concentrations.
