Know before you buy
Yes, HASA Granular Chlorine is specifically formulated for use in spas and hot tubs to ensure the water remains sanitized and safe.
The granular form is designed for rapid dissolution, which helps prevent residue from settling on the bottom of your spa and ensures the chlorine is evenly distributed throughout the water.
While its primary function is sanitization, using this product as part of a regular maintenance routine helps keep your spa water crystal clear by eliminating bacteria and organic contaminants.
Store the bucket in a cool, dry, and well-ventilated area away from direct sunlight and moisture. Always ensure the lid is tightly sealed after each use to prevent the chlorine from losing its potency.
This product is primarily intended for routine sanitization. While it can be used to maintain chlorine levels, you should always check your specific spa manufacturer's guidelines regarding shock treatments and dosage requirements.
