purigen question.

[madugo]

hi all..
i am about to add some purigen to the canister, but I've noticed that it described as:Not to be used with any products with slime coat in them as this can cause the product to become toxic.
Is this the true statement? if so what products i have to watch out for that may have slime coat in them? as of now i mix my own Sodium Thiosulfate solution as Dechlorinator when i do my water change..and pretty much that is the only thing i am going to add in there, of cause medications will be added if applicable.
So i should be good?
and also, is it bad or any benefit if i put more purigen in filter than what it suggests? i think it suggests 100ml can do for 100g of water, what if I do 200ml if the fish load is larger? any benefit or just unnecessary?
thanks.

I've used it in my overflow boxes before, but never inside a can....I also used it along with stress coat......I don't use it anymore, but I can't say for sure or not whether this combination was responsible for any fish losses...???

seems like i found a part of the answer to my question.
Q: Does AP Stress Coat foul/ruin your Purigen product?
A: If they use an amine based polymer it will not foul the resin but will render it non-regenerable. What amine based polymers will do is bond not just to Purigen but to any organic scavenging resin as well as any ion exchange resin and when you attempt to regenerate the resin they will then bond with the chlorine to form chloramine which can be released into the aquarium. This is not just an issue with Purigen but with all resins being sold in the pet trade. The problem only occurs when one attempts to regenerate the resin, there is no problem unless you wish to regenerate the resin you are using. Seachem products do not contain amine based polymers and are safe to be used in conjunction with not only our resins but also with other companies resins.

so as i can understand, as long as i dont regenerate the purigen, everything should be fine? Which i am not going to plan to regenerate the purigen at all..i am just going to buy new ones every 6 month than playing the risk..
also, any input on the purigen and Sodium Thiosulfate combination?
