Hi all,
I’m starting up a UNR R90 and looking at seeding it with the TBS Sand and Rox box, which is 6 lbs of live sand and 2 lbs of premium nano rock. That would go in the refugium section of the sump with some chaeto above it and a UNS refugium light. My only concern is hitchhikers. I had vernatids in a prior tank, and I really, really don’t want to go through that again. Is there a reliable way to make sure nothing like that comes in on the rock? I know I can inspect it visually but I worry about things I can’t see.
