i just set up my refugium and I put a sand base in it from the tank I was breaking down. Did I screw up? said:
Naw... its just something I don't recommend if its not already in. Just keep an eye on the sand itself and vaccum it when you do water changes. Its not a major deal, but can get quite a bit of debris in it over time. Putting some cleanup crews in there helps.. things like Nassarius Snails, Cucumbers, Small Conchs that kind of thing. Nassarius typically don't climb the sides, but they will occasionally so if you use them in the sump, check periodically and rescue any that climb over. You don't want those getting into a pump or return line etc.
