I am helping a friend of mine with his aquarium. We are building a water polisher and we are going to use purigen. I believe he has been using stress coat or some other dechlor product. So my question is how long do amines stay in the tank and should I really consider just doing a 100% water change?

If you suspect there are amines present as used to disinfect drinking water they degrade very slowly on their own. A water change maybe appropriate if there is no other means to degrade the amines

We are going to do a large water change, around 70 or 80 percent and we will use prime to treat the new water. Will prime bind the amines so we dont have to worry about the purigen becoming toxic as that is my main concern is when he recharges the purigen.

I used a stress coat product a month before I added purigen, and when I recharged it, it didn't kill my fish. It was the Tetra water conditioner that I know has amines in it. I think amines are a problem with the conditioner you use to neutralize the bleach, they bind with the chlorine and cannot be broken down by a conditioner.

Seachem - Purigen

Purigen and API stress coat- Conflicting information - Seachem - Aquatic Plant Central

Here are 2 links regarding this issue:

Note the vague 'caution' by Seachem in the 'Directions' section for Purigen use.

It seems the issue relates to using dechlorinators (having amine-based stress coat additives) during the re-charging process, when chloramines may be formed.

@discuspaul As usual you provide some solid info. The link provided answered my question. Thanks to all who replied.

Avoid any risk by simply using Seachem Prime as your de-chlorinator during re-generation, which I've been doing for years with Purigen.

Bah. I prefer Seachem Safe. Much better bang to the buck.

I only use prime but I am doing all of this for a friend so I will have to make sure he understands. He isnt the hobbyist most on tpt are. BTW is purigen great or what? I started using it just under two weeks ago and cant believe the difference.

This is for a friend and I think the liquid will be easier and prime is easier to find in our area where we have to order safe over the internet which this guy wont want to do. He isnt really a hobbyist, just a dude who has a fish tank. .

amines should be completely avoided when using purigen. But when in doubt, email seachem. They're always super helpful and respond quickly.
