Macro algae dip?

[Sophie"s mom]

Good morning all, so a question, for those who saw my posts yesterday, obviously I purchased some macro algae that, as it turns out had a few (3) different hitchhikers on it. Clearly not smart on my part, but it never occurred to me to dip/quarantine algae. Is there any type of dip that can be used on macro algae?

Following. I have never dipped my microalgae. but maybe depends on where we purchase them from.
