Chlor Brite and Other Types of Pool Shock

There are three main types of pool shock: chlorine-free, dichlor, and cal-hypo. Understanding which type is best for you depends on your pool's specific needs.

Before we talk about the various types of pool shock, let's first talk about the main reasons why it's important to use it. It can be used when the levels of chlorine are low, due to an algae bloom, or it can be caused by a fecal contamination issue. Aside from these, shock can also be beneficial after a major weather event, such as heavy rains or strong winds, which can deposit debris and dirt in the water.

Before you decide which type of shock to use, it's important to understand the various issues it can address.

Let's dive in!
