About
Who We Are
Lettradex Solution (formerly Lettradex Corporation) is based in Kuala Lumpur, Malaysia. We have been the official distributor of the Caribbean Clear Pool Treatment System in Malaysia for over 30 years, since 1996.
Caribbean Clear is built on NASA-developed water purification technology, adapted for pool and spa use since 1982. It’s an alternative to conventional chlorine treatment used by properties across Malaysia — from private homes to condominiums and hospitality facilities.
Why caribbean clear?
Less Chlorine. Less Maintenance. Better Swimming
Traditional pool maintenance often means regularly measuring, adding and adjusting chemicals just to keep the water clear. Heavy daily dosing is also why eyes sting, skin dries out, and pool equipment wears down faster than it should.
Caribbean Clear takes a different approach. Copper and silver electrodes release controlled levels of ions into your pool water — allowing your pool to operate with substantially less reliance on chlorine. By reducing your pool’s reliance on chlorine, Caribbean Clear helps create a gentler swimming experience while providing continuous control of algae and bacteria.
- Uses significantly less chlorine
- Gentler on eyes, skin & hair
- Helps control stubborn pool algae
- Reduces chemical exposure to pool equipment
- Simple, low-maintenance operation
The result? Clearer water. Less chemical dependency. Less work for you.
And because the ionization process works automatically while your filtration system is running, there is no need to manually dose the pool every day. Caribbean Clear works alongside your existing filtration system and still requires appropriate pool sanitation and water balancing.
NASA-DEVELOPED TECHNOLOGY
Built on water purification technology created by NASA, Caribbean Clear has used this space-age science since 1982. Silver ions to control bacteria, copper ions to control algae — refined into a scientifically proven formula specifically designed for your pool.
NASA’s own publication report that Caribbean Clear-treated water can meet standards comparable to EPA drinking-water requirements—a level of proven safety few other systems can claim.
The system pairs a long-lasting 93% copper / 7% silver electrode with a compact controller, automatically releasing the exact ions needed directly into your pool’s existing circulation system.

How Does Caribbean Clear Compare?
A side-by-side look at ABOUT how the most common pool treatment systems actually perform.
| Traditional Chlorine | Salt Water Chlorinator | Caribbean Clear | |
|---|---|---|---|
| Daily Upkeep | Manual testing & dosing every few days | Automated, but cell needs regular upkeep | Weekly copper test only |
| Chlorine in the water | 1–3 ppm | 1–3 ppm — still chlorine-based | ~0.4 ppm |
| If maintenance lapses (holiday, power cut) | Water quality drops within hours | Stops producing chlorine when off | Stays protected for days |
| Skin & eye comfort | Irritation common | Marketed as gentle, but same chlorine range | Noticeably gentler |
| Equipment wear | Corrosive over time | Salt can corrode metal fixtures & heaters | Reduced chlorine load, less wear |
