Hello I'm plumbing a 18 inch cube aquarium to my 60 cube and going for a macroalgae/ refugium with seahorses. Right now I have it plumbed to the sump and have live sand and dry rocks. I put everything from my old in-sump refugium. I'm wondering if I could get some advice from people who have done this or something similar? What kind of macroalgae, gorgonia or sponges would be good for this? Also any seahorse type or number suggestions? Thank you
