CLEARANCE: Premier Blue 4-in-1 Chlorine Tablets 1KG (Faded Label) - £8.99 each or 2 for £17

⚠ Clearance stock — faded labels only. The labels on these tubs are a bit faded. The tablets inside are perfect: same product, same Premier Blue 4-in-1 multifunctional formula, same use-by date. We’re shifting them at cost price to clear shelf space.

Premier Blue 4-in-1 Multifunctional Chlorine Tablets, 1KG tub of 20g tablets (50 tablets per tub). Each tablet sanitises, stabilises, clarifies and treats algae in one go — everything you need to keep pool or hot tub water clear, in one slow-release tablet.

What each tablet does

• Sanitises — high-strength chlorine kills bacteria and keeps water hygienic
• Stabilises — built-in cyanuric acid stops UV burning off your chlorine in summer sun
• Clarifies — coagulates fine particles your filter can’t catch on its own
• Tackles algae — algaecide blended in to stop green water before it starts

How to use

1. Place tablets in your skimmer basket, floating dispenser, or in-line chlorine feeder.
2. Start with 1 tablet per 1,000 litres of pool water as a guide, then adjust based on test readings.
3. Test chlorine and pH at least twice a week. Each tablet dissolves over 3–7 days depending on flow and temperature.

Safety

• Never drop tablets directly into the pool — they can bleach or stain the liner.
• Never mix with other pool chemicals or household cleaners. Trichlor reacts dangerously with calcium hypochlorite, ammonia, and bleach.
• Store in original tub, dry, away from kids and pets. Keep the lid sealed.
