Hi, I know that stress coat is immediate in its effect, however, was curious to know how long it stays active in the water. I have searched a while and only found a few references to 24 to 48 hours. Can anyone confirm this. Ordered some purigen and prime but want to make sure the stress coat is completely dissipated before using. The details around purigen and stress coat are very confusing. Seachem techs seem to suggest on their forums that it's safe to use regularly, just not during regeneration while their FAQ states any amine product will make it toxic and makes no mention of it only being during regeneration. Guess I would prefer to be safe than sorry. All feedback welcome. Thanks.
