About this product

The Clearwater 1 kg Multifunction Chlorine Tablets are a convenient solution for maintaining sparkling clean water in your pool or hot tub. Designed to tackle a range of issues, these tablets offer a comprehensive approach to water care, making them ideal for both experienced pool owners and those new to managing their aquatic environments. They’re particularly well-suited for above ground pools, paddling pools, and hot tubs where maintaining clear and hygienic conditions is crucial.

These 50 x 20g tablets are formulated as a powerful 4-in-1 treatment – sanitising, stabilising, an algaecide, and a water clarifier all in one. Rather than direct application, which can be messy and less effective, Clearwater recommends utilising a floating dispenser or chlorine feeder, such as the ChemConnect, for a slow release of the chemicals. This allows for consistent control over water chemistry, lasting approximately 3-5 days per dose.

The tablets slowly erode over time, providing long-lasting application and minimising waste. Clear instructions are provided on the packaging to guide you through the simple process of maintaining your pool or hot tub’s water quality. It's worth noting that a floating dispenser isn't included; these tablets are designed for use with compatible feeders.

For best results, consider purchasing a suitable chlorine feeder alongside these tablets. The Clearwater CH0019 offers a trusted and reliable solution for keeping your pool or hot tub looking its best, backed by a significant number of positive reviews from satisfied customers.
