One tablet, one week, one happy pool.
CrystaLux Multifunctional Chlorine Tablets in 200g format are sized for larger residential pools. Drop one into a floating dispenser or skimmer and it sanitises, controls algae, clarifies, softens and stabilises for up to a week, depending on water temperature and bather load.
Important Tablet Size Guidance
These are large 200g multifunctional chlorine tablets, designed for larger swimming pools and use in a floating dispenser, skimmer basket, or chlorine feeder.
Each 200g tablet is intended to treat up to approx. 10,000 gallons / 45,000 litres of pool water, depending on water condition, sunlight, bather load, and chlorine demand.
For small pools, hot tubs, spas, inflatable pools, or pools around 10,000 litres, we recommend using 20g chlorine tablets instead, as they offer easier and more controlled dosing for smaller water volumes.

The CrystaLux Standard
CrystaLux was created for people who believe clear water should feel effortless.
Your pool or hot tub is more than water in a shell. It is where summer slows down, where weekends begin, where guests gather, and where your home feels just a little more special. That experience deserves products that feel as considered as the space itself.
That is why CrystaLux takes everyday pool care and makes it cleaner, simpler, and more refined. No confusing jargon. No messy guesswork. Just premium water-care essentials with clear instructions, practical dosing, and a design that looks as good as the water you are working towards.
Every CrystaLux product is part of the same promise: confident care, clearer water, and a pool routine that feels under control.
Because when the water looks right, everything around it feels better.
