Granular vs Liquid Chlorine
Both granular and liquid chlorine are effective at disinfecting pool water by killing bacteria, viruses, and other harmful microorganisms. Here are some differences between the two:
​
Concentration: Liquid chlorine is typically more concentrated than granular chlorine. This means that you'll need less liquid chlorine than granular chlorine to achieve the same level of disinfection.
Cost: Granular chlorine is generally less expensive than liquid chlorine on a per-dose basis. However, since liquid chlorine is more concentrated, you'll need to buy it less frequently.
Storage: Granular chlorine is relatively stable and can be stored for long periods of time without losing effectiveness. Liquid chlorine, on the other hand, has a shorter shelf life and should be used within a few months of purchase.
Application: Granular chlorine is typically added to the pool by scattering it over the surface of the water or adding it to a feeder. Liquid chlorine is usually added directly to the pool through a dispenser or by pouring it in around the perimeter of the pool.
pH Level: Granular chlorine has a lower pH level than liquid chlorine, so using it can cause the pH level in your pool to decrease. This means that you may need to adjust the pH level after adding granular chlorine.
​
Ultimately, the decision between granular and liquid chlorine will depend on your individual preferences and needs. If you prioritize cost and storage stability, granular chlorine may be the way to go. If you prioritize ease of use and concentration, liquid chlorine may be the better choice.
