## Overview

Clearwater 1 kg Multifunction Chlorine Tablets deliver a powerful 4-in-1 formula that sanitises, stabilises, prevents algae growth, and clarifies pool and hot tub water. Designed for slow release over 3-5 days, these easy-to-use tablets fit floating dispensers or feeders, ensuring long-lasting, consistent water care. Ideal for hot tubs and above-ground pools, they come with clear instructions for safe, effective maintenance.

## Description

From the manufacturer 4-in-1 Multi Functional Tablets Clearwater Multi-Function Chlorine Tablets are an incredibly simple way to maintain clear and hygienic pool or hot tub water. These multi-function chlorine tablets are designed for use with floating dispensers or the Lay-Z-Spa ChemConnect. They will slowly erode over a period of 3 to 5 days, depending on the amount of water flowing over them. These multi-function chlorine tablets are an easy and convenient way of keeping pool and hot tub water clean. As well as containing chlorine, which kills bacteria and other organisms by disinfecting water, the tablets also contain an algaecide solution that prevents the growth of algae. The chlorine tablets also contain a water clarifier. Some debris and particles that find their way into water, such as dead skin and algae, are too small to be trapped by the filter system. Clarifier contains flocculants, which bind particles together so that a filter can trap them, producing clean and sparkly water.

Review: Excellent quality, highly reliable, would recommend - Great value for money. No skin irritation. Use this with a slow release floater for our large outdoor pool mostly (3 tabs per week in a large outdoor pool to keep levels healthy). So the chlorine content is suitable for our pool and we use 1-2 tabs in our hot tub (6 person) so would say chlorine content is slightly higher than you assume. Dissolves slowly. Sometimes after 2-3 weeks when slow dissolving in pool it may not yet be time to replace, but in general fairly stable. Highly recommend. Brought our pool back from the abyss 🤣
Review: Great product - Wouldn't buy a different product! These are super easy to use and work very well. Last a long time. Never had an issue. Keep hot tub clean and smelling fresh. Would recommend.
