GreenStory Global Cyanuric Acid

It’s basically an ion exchange resin with granular activated carbon … it’s not going to work. Chlorinated water destroys ion exchange resins and the resin+GAC is going to pickup everything in the water.

Once again - science misapplied in the pursuit of profit.

Basically the same stupid idea as CuLator, in my opinion.

Chelok is Periodic Products’ patented series of chelating polymers which are the result of more than two decades of
biochemical research and development.

Rather than using contaminated wastes with chemical precipitants or ion exchange resins, these water insoluble polymers adsorb dissolved heavy metals, which can be easily filtered to separate the metal-containing polymers.

The recovered metals in this process can increase yields providing additional economic and environmental benefits.

Since Chelok chelating polymers retain their metal-binding ability after metals have been recovered, the polymers can be reused.

The question to ask is how does it specifically pickup the cyanurate anion? Ion exchange resins are charge specific and don’t discriminate between which ions get attached to it. The main factor that determines how the resin operates in based on concentration differences. This is how standard cationic resins work - the resin doesn’t care if it’s a sodium ion or a calcium ion attached to it. What drives the exchange is the fact that you wash the resin in a super concentrated brine solutions and so the sodium concentrations is thousands of times higher than the calcium concentration. This forces all of the calcium out of the resin where it is replaced by sodium. Then, when you run normal water through it, the calcium concentration is higher than the sodium concentration and so the sodium leaves the resin while the calcium is attracted to it.

In an anionic resin, the same rules apply. So in pool water you have three major anions - chloride (Cl-), carbonate (HCO3-), and cyanurate. The chloride concentration is pools is usually 10 times higher than the others and the cyanurate is roughly equivalent to the carbonate concentration.

So how exactly is the resin going to differentiate between the cyanurate and the chloride when the chloride levels are so much higher?

It doesn’t. And so that resin is likely to absorb mainly Cl- ions and give off OH- anions. The cyanurate will exchange at an amount proportional to its relative concentrations.

According to the lead research scientist (A graduate of ASU I might add) you need to use specially tuned magnets that clamp on the pipe and charge the CYA molecules with a frequency that is identical to the resin, which makes them lock together.

Don't forget to also add a magic sponge and a copper pipe in your other skimmer for extra super duper effectiveness.

I bet he figured that out while hanging out with Pom squad on the campus quad when they were working on their tans … I always imagine their discussions must be incredibly deep -

It’s just another attempt to solve a problem that shouldn’t exist in the first place.

Activated carbon doesn’t work with passive flow.
Melamine complex is non specific in terms of which anion it attracts and there is way more chloride ions.
The melamine complex can cause staining - they sell other products to fix that.

But the kicker. They say it removes 10ppm CyA per week. Just ignore the modern international standard measurement units. In my pool 10ppm CyA is ~200gms of dry CyA, that’s just over 3/4’s of a cup. There is no way in hadies that little pouch of carbon will absorb 200gms or 3/4’s of a cup of dry CyA.

And even if it could, for those that are up in the +200ppm range thats 10 or more packets which would have to be north of $300-400 worth. A drain and refill would be more cost efficient and actually work.
