Cupramine, Evaporation and Top Offs

[kesh]

Hi, few quick questions?

1. Does cupramine levels increase with evaporation or remain at levels pre-evaporation?
2. If increase, i would then need to constantly maintain it at certain water level?
3. If same, do i need to add cupramine to top off water cause it then seems i would be diluting the water with top offs?

I lose around 10% water volume weekly to evaporation

I have read the answer somewhere but cant re-trace it and not much time to spent due to exams. Sorry. Cheers

Cupramine does not evaporate, but pure water does,

So as you lose water, it concentrates, then replacing the evaporated water returns it to where it was.
