Blue Horizons Granular Shock 5kg - Shock dose for pools & spas Description

Blue Horizons is a leader in swimming pool and hot tub treatments.

Produced to high standards ( no cheap low strength imports here! )
These high strength, non stabilised chlorine granulers are great for shock dosing your pool or spa.
Ideal as a once a week or bi weekly addition to help break down a build up of debris and organic matter in the water - often shown as a haze.
Helps reduce the strain on your daily sanitiser and filter.

High strength means you use less. Not all granular shock doses are the same and a lower strength will just cause you to use more!

Good product which I have used for several years with good results. Keeps pools water in good condition. Product was ordered from Affordapool who gave best price. Delivery was as promised and packages safely and securely. A good reliable company would recommend them and will use again for my pool supplies.
