Re: Prime Building Up Over Time?
No, Prime only builds up for every instructed dose added (e.g. a 2x dose for the entire aquarium would mean you can replace all the aquarium water with chloramine-treated water, but you would have to dose after adding the water or replace 50% of the water only.). I said "2x", because if you had already dosed once, then you would have to does again. To make things simple you can still do the 1x recommended dose.
It lasts only 24 hours per instructed dose (i.e you dose to the proper liter/gallon of water).
It doesn't become toxic no matter how much you over dose, but it will deplete oxygen a bit more (that's what some people may refer to it as being toxic when they see their fish die by suffocation from extreme overdosing i.e a 20x dose).
I beleive it oxidzes in the aqaurium water or evaporates as a type of gas during 24 hours from the/an intial dose.
