i would mix it right before youre ready to use it, but i can imagine it would be okay to store it for a little while
clove oil in small doses is safer than MS-222, although, as said, not FDA approved. its the FDA, though, and theyre all about money and clove oil just isnt profitable, esp when its pretty easy to refine. anyway, thats for another discussion, lol. we had some of the brookies under for maybe a few hours and they were fine. the times we used MS-222 for spawning brown trout, they were only in it for less than an hour. i'm not sure of the upper limits, though. would def depend on concentration.
