Purigen, amines, and chlorine

[Sebae]

Trying Purigen for the first time. I am wondering, as seachem mentions amine products interacting with chlorine during regeneration to produce chloramines, a couple of things.

1) Would amino acids bound to Purigen interact with chlorine to produce chloramines during regeneration?

2) Would it be possible for trace chlorine from my bleach washed filter socks to interact with any amino acids bound to Purigen still in the aquarium to form chloramines?

Any advice would be appreciated!

Thanks

Do we know that amino acids are bound by Purigen?

Not sure if it would, but if it did - during regeneration with bleach the chlorine is in such excess that any chloramine would be reacted away entirely.

2) Would it be possible for trace chlorine from my bleach washed filter socks to interact with any amino acids bound to Purigen still in the aquarium to form chloramines?

Those tiny levels of chlorine from washed material would find plenty of things to react with in the water before it would find its way to the purigen.

But seachem said it does
(I've never seen any evidence it does either)

They sell miraculous products. I was trying to think of ways to prove Purigen adsorbs anything.

It's most likely just a water softener resin optimized for tannin removal plus 80 tons of marketing gobbledygook.

If you put it in tank water, it goes in white and then over some days will develop a yellow brown. If you regenerate it in bleach it'll go back white.

But then again, the above is also true of my socks.

OK, I’ll try my socks first

I was thinking about the “so what” challenge product claims. Can I brown up a sample of Purigen, grind to a powder and monitor oxygen consumption in aquarium water. If there was a bunch of O2 used, I would feel a little better about the product because it actually did something useful like remove nutritious carbon rather than just act like expensive GAC to decolorize water.

I'm not sure why there's a concern about chloramine when the process involves a ton of bleach/chlorine anyway. Both would be undesirable to get into the tank so the material should be well rinsed prior to use.
