Spirulina for frozen food?

[MikeyZO]

I have a ton of spirulina powder for gut loading baby brine shrimp, just wondering if anyone has tried using it on frozen mysis before feeding, and how do you go about it? I’ll never use it all for the brine before the expiration date lol

I've heard of soaking in Selcon before, but not spirulina. Not sure how much would stick.
