How much fluid in IC-tank

[Nikohm]

i just been installing a Lethal perf IC-reservoir. And the fit was perfect. But now to the question how much fluid should there be in it ?? (sry for newbie question)

Should it be half way up ore more ?

It didn't come with any info that tells you? If not, probably the same level as the stock reservoir, but I am not positive about this.
