Product Information
Full details
Blue Horizons Granular Shock Chlorine is ideal for pool owners seeking a powerful, stabilizer-free sanitization solution to maintain crystal-clear water. By utilizing 65% available calcium hypochlorite, this treatment effectively destroys swimmer waste and prevents algae outbreaks. While it provides rapid sanitization and disinfection, users must monitor pH levels closely and wait for chlorine levels to stabilize before entering the water, as the rapid release of chemicals can cause temporary cloudiness.

FAQs
How long must I wait to swim after shocking?
You must wait at least 30 minutes after application, and ensure that chlorine levels have dropped below 5mg/l before entering.
Can I add the granules directly to the skimmer?
No, you must pre-dissolve the granules in a clean plastic container of water first to avoid localized chemical damage and ensure safety.
Will this product affect my pH level?
Yes, as with most chlorine-based shocks, it can influence pH. Always test and adjust your pH to the 7.2-7.6 range before and after treatment.
Is this safe for all pool types?
This product is suitable for most pools, but always check your pool surface manufacturer's instructions regarding the use of calcium hypochlorite.
How often should I use this for shocking?
Use it whenever water clarity is compromised, after heavy usage, or as a preventative measure following periods of extreme weather.
Troubleshooting
Water remains cloudy for more than 24 hours
Ensure the filtration system is running continuously and check for any debris clogging the filter media.
Chlorine levels remain too high for swimming
Wait longer for the chlorine to naturally dissipate or perform a partial water change if immediate use is required.
Difficulty dissolving granules
Use a larger volume of water in your plastic mixing container and stir thoroughly with a plastic stirrer before pouring.
Pros and Cons
Pros

- Rapidly eliminates and prevents algae growth

Cons
- May cause temporary cloudiness immediately after application

Setup, Compatibility & Care
Before applying the shock, it is critical to verify your pool water chemistry. Use a test kit to ensure your pH level is balanced between 7.2 and 7.6; failure to do so can reduce the product's effectiveness.
- Always pre-dissolve the required amount of granules in a clean plastic container filled with pool water.
- Add the dissolved solution directly to the pool water near the water inlets.
- Keep the circulation pump running for several hours to ensure even distribution.
- Store the container in a cool, dry place away from direct sunlight, moisture, and incompatible chemicals, keeping the lid tightly sealed at all times.
