The combination of the COVID-19 pandemic and the 2021 hurricane in Louisiana had devastating effects on the production of many key ingredients used for pool and spa products, including chlorine tabs.

The nationwide shortage of trichloroisocyanuric acid (TCCA) with CYA is making it very challenging for retailers to maintain their supply. But thankfully, we have an answer.


Cal Hypo saves the day

Cal Hypo is the perfect replacement for chlorine tabs because it does not contain stabilized chlorine, so there’s no risk of overstabilization or chlorine lock. Preventing chlorine lock also helps stop chlorine odor, cloudy water, red eyes and itchy skin. With Cal Hypo, the result is clean and visibly brilliant pool water.

Chlorine is a key ingredient in many shocks and sanitizers. But too much stabilized chlorine can be a problem. Many pool owners use stabilized chlorine products that contain CYA, or cyanuric acid. While the chlorine eventually dissipates, CYA does not. So, when you add more stabilized chlorine (often in the form of tabs) to your pool water, the CYA builds up, which causes overstabilization — otherwise known as chlorine lock.

Our inventory is stocked, and we’re ready to help you tackle any challenge with our range of Cal Hypo sanitizer products, like HTH® Pool Care Chlorine Granules Ultra and HTH® Pool Care Chlorine Skimmer Tabs.

As always, we’re here to help. If you have questions, contact our help line at 1-866-HTH-POOL or talk to our experts with our live chat!


Please read the following important reminders before adding pool chemicals to water:

• NEVER mix products together or dissolve before use.

• ONLY enter pool when FAC levels are below 4 ppm to prevent risk of bodily harm.
