Product Description

Hot Tubs Shock

Next Gen Hot Tubs Shock – Calcium Hypochlorite Pool & Hot Tub Treatment – 2kg (4.4 lbs)

Next Gen Hot Tubs Shock – Calcium Hypochlorite Pool & Hot Tub Treatment – 2kg (4.4 lbs) – 70% Available Chlorine – Powerful Algae Eliminator & Water Clarifier

Refresh your spa or pool water with this high-strength calcium hypochlorite shock. With 70% available chlorine, it destroys organic contaminants, eliminates algae, and restores water clarity fast—ideal for both hot tubs and swimming pools.

Why Choose This Product?

Granular Chlorine for Pools

Potent Oxidizing Power:

70% available chlorine rapidly breaks down oils, sweat, cosmetics, and other unwanted contaminants.

Hot Tub Treatment

Effective Algae Control:

Kills and prevents green, black, and yellow algae growth.

POOL SHOCK

Crystal-Clear Water:

Acts as a clarifier, improving water transparency and sparkle.

Pool Shock Treatment

Versatile Use:

Suitable for both saltwater and freshwater systems, in-ground or above-ground pools, and all spa types.

How to Use

Potassium Monopersulfate (MPS)

Balance Your Water First

pH should be 7.2–7.6 and alkalinity between 80–120 ppm. This ensures effective chlorine performance and prevents irritation.

STABILIZED CHLORINATING GRANULES

Measure the Dose

Add 20g per 1,000L of water (or 75g per 10,000L) weekly for maintenance. Increase dose after heavy usage or visible algae.

HOT TUB WATER BALANCER

Application Method

Add directly to the water with pump running, or pre-dissolve in a bucket for even distribution.

POOL CHLORINE GRANULES & SPA SANITIZER

Let Circulate & Enjoy

Allow 15 minutes of circulation before use. The fast-dissolving formula quickly sanitizes without harsh residue—leaving water clean, fresh, and ready to enjoy.
