Wanted: Chaeto Macroalgae OR OTHER MACROALGAE

[Istrom]

Hey guys,

I'm looking for some Macroalgae for my marine refugium, I converted a dry/wet sump so I'm not looking for any plants that NEED to be rooted... eventually I may add sand and some LR, but for now I just need some macroalgae that will float or attach to the white grate I have.

Thanks.
