Fertilizing macroalgae?

[LordJoshaeus]

Hi everyone! I have decided to add some macroalgae to my quarantine jar I am setting up. The problem is that the jar will receive 100% weekly WC's and likely won't accumulate much for nutrients when it is not quarantining any corals. How do I go about fertilizing macroalgae without causing any problems? Thanks

F2 or chaetogrow would work
