Over in this thread Pool Opened: High CyA (147 ppm) and FAC (15 PPM) the OP mentioned using a CYA filter from Leslie's. It was pretty easy to track down and they are kind enough to even include the SDS link on their website

CYA Remover | GreenStoryPoolandSpa

End chlorine lock and remove cyanuric acid (CYA) from your pool quickly and effectively with GreenStory Global's CYA Remover. No need to drain your pool! Save money, time, and WATER!

Their claims don't sound trustworthy, such as claiming it will remove 10 ppm CYA per week and omitting any limit to how much CYA it will remove. I was wondering if some more chemically minded people might want to weigh in on whether there's even the tiniest bit of potential in the polymer listed or if the thing is nothing but an $80 placebo.

I think most of us believe there is a small, NATURAL degradation of CYA in a pool. I also think that degradation is temperature related. The amount of degradation seems to vary between almost zero to maybe 15% monthly

I think greenstory may use this naturally occurring degradation as "proof" that their remover works and you, the end user, simply needs to add more.

I have always sensed the pool community REALLY wants this to work and will grasp at the smallest particle of truth to cling to. I am not sure why.

To me, it is the latest "magic potion" that is a completely unnecessary (and unproven) additive for pools.

“Keys to Success while using our CYA Remover:
  • Switch to liquid chlorine or shock that has no stabilizer in it…”

That was the first bullet. So switch to TFPC 🤣 This is more seesaw, whack-a-mole. We sold you tabs and pucks and kits that increased your CYA beyond human comprehension all while telling you any chlorine level over 3 ppm is dangerous, and you never had enough chlorine in your pool all this time and we caused that problem. So now we will tell you to switch to liquid chlorine only BUT we refuse to lose money and you must buy this contraption to save you from draining your pool.

No usage warnings about how to prevent it from removing too much CYA, because if you do well we can just sell you more pucks and tabs or stabilizer for that! Whack whack whack.

Idk, I’m being snarky cuz they are wolves sitting at a table of sheep trying to convince them that they have their best interest at heart. Lol. Maybe this is something that “could” potentially work in certain situations, but what’s in it?? How do we know it won’t upset the balance of the water in other ways and keep the whack-a-mole game going? Just because they say it won’t?

Eager to hear from our scientists after they review the data.
 
CAS Number: 0007440-44-0 is Activated charcoal.

CAS Number: 0069011-17-2 is Methanamine, N-methyl-, reaction products with chloromethylated divinylbenzene-ethenylethylbenzenestyrene polymer

How does our CYA Remover work?

Our CYA Remover pouch works by removing CYA through a simple process of adsorption, which allows for the reduction of CYA in the water without draining your pool.

The filter media in the pouch has a large surface area and a high binding capacity, resulting in the rapid removal of CYA from the water.

Maybe it combines with CYA like Melamine in the CYA test?

I suspect that the claims are greatly exaggerated.

I think that it is unlikely that the pack can adsorb enough CYA to make a significant difference.

That's my guess, that the polymer is supposed to bind with the CYA to form something that can then be bound to the carbon. Even if it works in principle there are a lot of things in the pool that will bind to the carbon faster.

Kind of like bioactive or CUlator, I wouldn't be surprised if it's rooted in a real process but in practice leaves a lot to be desired.

10 ppm does not make sense because it depends on the pool size.

The pack is not going to pull out 40 oz of CYA from the water.

They say patent pending, which really means nothing other than they have applied for a patent, which a search does not show any patent being applied for.

Does the filter change the pool chemistry?

Other than reducing the CYA by about 10 ppm per week, there is no impact on pool chemistry.

10 ppm is about 13 oz in a 10,000 gallon pool.

20,000 = 26 oz.

30,000 = 40 oz CYA.

This seems like a good enough place to ask this question I wondered about the other day... Since a pool developing ammonia will destroy the CYA, if someone wanted to remove CYA, could they add some ammonia to the water, and then SLAM it to overcome the ammonia?
 
Ammonia does not destroy CYA.

CYA gets converted into ammonia by bacteria.

If you introduce the bacteria, it might eat the CYA and convert it to ammonia and then you SLAM for ammonia.

This is the basis for Bioactive CYA reducer, but it does not work in practice for most people.

You would first have to show that ammonia does destroy CyA. I wasn’t aware that it does.
 
Activated carbon does work as a filtration media but it’s normally applied in such a way that all your water to be treated flows through it. When placed in the skimmer most of the water will simply flow around it and the volume of product to pool size is tiny. There is a risk of blocking the skimmer.

And then there’s the methanamine, N-methyl-chloromethylated divinylbenzene-ethenylethylbenzenestyrene polymer - no thanks, not it my pool.

How does the activated charcoal only absorb the CYA, and not the Chlorine and everything else in your pool water - as I understand it, there is only so much a carbon filter can absorb, and once it's full of chlorine, there is no where for it to absorb CYA or anything else right ?

It's cheap enough for people to try it, but not expensive enough for people to sue over when it doesn't work. I'm sure it'll be the latest thing at the pool store "Add two of these to your skimmer when you open, and then one a month to maintain your CYA levels"...while selling you stabilized pucks that add the CYA you are spending $80/month on pouches to remove.

In my opinion, it is just another worthless scam product claiming to solve a problem created by the stores in the first place.

I seriously doubt that there is, or ever will be, a patent or any legitimate studies that show what effect the product really has.

As an anion exchange resin, it might pick up a few molecules of anions as they make contact, so you might get 1 to 2 milligrams of CYA trapped in the resin.

So, to see any useful effect, you might need about 1 million pouches of the product, which is a pretty good deal in my opinion.

Uses
Weakly basic anion exchange resin can be used in conjunction with strongly basic anion resin to treat water containing high concentrations of mineral anions or possibly with high levels of organic pollutants.

It is an excellent choice for desalination and meets the requirements of the US Food and Drug Administration Food Additive Regulations 21CFR173.25.

Manufacturing Info：

Methanamine, N-methyl-, reaction products with chloromethylated divinylbenzene-ethenylethylbenzene-styrene polymer: ACTIVE|XU - indicates a substance exempt from reporting under the Chemical Data Reporting Rule, (40 CFR 711).

Anion resins may be either strongly or weakly basic.

Strongly basic anion resins maintain their negative charge across a wide pH range, whereas weakly basic anion resins are neutralized at higher pH levels.

Weakly basic resins do not maintain their charge at a high pH because they undergo deprotonation.

They do, however, offer excellent mechanical and chemical stability.

This, combined with a high rate of ion exchange, make weakly base anion resins well suited for the organic salts.

For anion resins, regeneration typically involves treatment of the resin with a strongly basic solution, e.g. aqueous sodium hydroxide.

During regeneration, the regenerant chemical is passed through the resin, and trapped negative ions are flushed out, renewing the resin exchange capacity.
