How to Use HTH Granufast Chlorine Granules
To maintain a safe swimming environment, it is important to regularly monitor and adjust chlorine levels. Follow these steps for best results:
-
Determine Pool Volume: Accurately measure your pool’s water volume to calculate the correct dosing amount. Contact us if you need guidance.
-
Test the Water: Check the current Free Chlorine level using your preferred water testing method.
-
Evaluate Chlorine Levels: If Free Chlorine is below 1 ppm, dose appropriately following the instructions below.
Recommended Dosing
To raise Free Chlorine by 1 ppm:
-
Add 18g of HTH Granufast Chlorine Granules per 10m³ (10,000 litres / 2,200 UK gallons) of pool water.
This precise dosing method ensures balanced chlorine levels, keeping your pool safe and clear.
Safety and Handling
-
Direct Dosing: Avoid inhaling dust, especially on windy days, to reduce the risk of respiratory irritation.
-
Cold or Low Circulation Water: For colder pools or low circulation scenarios (e.g., winter closures), pre-dissolve granules in a bucket of warm water before adding to the pool. This ensures even distribution and prevents granules from settling.
