Refugium Substrate

[kadiya]

Hi does anyone know what substrate is better to use in a refugium? I am planning to get a HOB refugium. I want to have macroalgae and mangroves in it and be able to sustain some copepods in there as well. Is mineral mud better or regular live sugar grain sand?
Thanks!

I have sand in mine I have geard that teh mud is better I just didn't want the mess for my tank was up and running and I heard it would make a big mess. Some do a 50/50 mix

I've read on here before that the mud is basically a rip off. I have a HOB with LS,LR and cheato and I have tons of pods.

Jsut a note the mud has nothing to do with teh pods. Pods will come regardless of substrate shoot my empty bottom refrug has a ton.
