refugium stock recommendations?

[lazycouch]

Hey everyone, i will soon be making this breeder tank my “hob” refugium and was wondering what i can add to it to make it most effective for its limited space. it is 0.5 gallons and measures 10”L 3.5”W 4”H. i think Chaeto is definitely in the plan (fuge is built primarily for nitrate removal) but maybe u guys suggest rock rubble only or something? hit me with your thoughts! my tank is 30gallons. i was essentially thinking chaeto (box has a decent current and would purchase a light), sand, and some other porous media but then again i’m only a couple months into the hobby! thanks !

Just the macro algae should be fine. If you wanna check the light with the forums feel free to post that too.
