Seachem Safe direct dosing

[scoobiemandan]

I have a 500l freshwater tank which I fill from the tap. Generally it takes a good 20 minutes or so to fill back up after a water change.

I have recently been informed that as safe doesn't contain stabilisers that it will only work for chlorine/chloramines for a certain length of time so would be better dosed over time rather than all in one go.

Can someone advise whether this is correct or not?

Hello scoobiemandan,

Could you please clarify what you mean by stabilizers?
