Can I put H2O2 in a vented dosing container

[14 foot reef]

Can I put H2O2 in a vented dosing container and dose my 1 ml per 10 gallons with my Apex DOS or will it lose its potentency not being in an air tight sealed bottle ?
Thanks in advance for your input

my bet: will slowly dissipate into freshwater if no internal pressure is kept via tight fitting lid + degradation by light if the container is not opaque. the soda goes flat mechanism

It breaks down quickly. Half life in the atmosphere is like 24 hours, or something like that.

assuming you are using store-bought brown bottle peroxide, or even ordering something like 12% food grade, and going through it in a month or less, my experience is that measurable degradation will be minimal. The half-life in atmosphere of 24 hours does come from a good source, but is referring to a different mechanism. A normal water-based solution is more like a percent or 2 in 3-12 months, highly dependent on cleanliness.
