Keep your hot tub water crystal clear and perfectly balanced with the H4920 Spa Essentials Spa Shock 6-Pack Kit — a convenient, pre-measured weekly shock treatment designed specifically for spas and hot tubs up to 2,000 litres.

Each kit includes six 48g single-use packets, making weekly spa maintenance quick, simple, and mess-free. This powerful oxidizing formula eliminates organic waste, destroys irritating chloramines, and restores water clarity — all while enhancing the efficiency of your sanitizer system.

Why Use Spa Shock Weekly?

Over time, hot tubs accumulate:

• Body oils and lotions

• Sweat and organic waste

• Chloramines (the cause of strong odors and irritation)

• Cloudiness from heavy bather loads

Spa Essentials Spa Shock breaks down these contaminants, keeping your water fresh, clear, and comfortable.

Key Features & Benefits

✔ 6 pre-measured 48g packets – no guessing
✔ One pouch treats up to 2,000L of spa water
✔ Built-in clarifiers promote sparkling clear water
✔ Fast dissolving and gentle on spa surfaces
✔ Eliminates chloramines and organic wastes
✔ Improves sanitizer performance
✔ Compatible with chlorine, bromine, or lithium systems

The built-in clarifier helps bind small particles so your filter can remove them more effectively, resulting in noticeably brighter water after treatment.

Best Practice for Use

• Use 1 packet per week under average bather conditions.

• After heavy spa use, add an extra packet.

• Add with pump running and allow water to circulate.

• Maintain proper pH (7.2–7.8) for optimal results.

This regular shock routine helps prevent cloudy water, unpleasant odors, and sanitizer inefficiency.
