Best Non Chaeto Nutrient Export for Sump

[QueenbeeChelsee]

Looking for ideas for nutrient export in my refugium other than Chaeto. I do have tangs so perhaps another macro would be an option to grow for feeding them.

My chaeto is growing fine but I want it to be multi functional if possible.

I started out with Red Ogo, and my purple tang goes wild for it. Not sure how it compares with chaeto for nutrient export, but so far it's doing the job for me.
