I am getting back into LF and am preparing to mix some XTOL. Would like to store it in a one-gallon glass container. I know "Google is my friend" but is there any recommendation for glass containers others have used successfully? Would not like to reinvent the wheel if there is a commonly accepted answer.

How do you remove the air and reduce the oxidation once the developer is used and the liquid level drops? Add glass marbles? I'd imagine one needs a lot once the levels drop quite bit. Or do you transfer to smaller bottles?

Thank you for ideas on both questions.
