Is it possible to have flatworms in your refugium but not in your tank? I've definitely got them in the fuge. Tried flatworm exit (FWE) but they came back after a few weeks. However, I don't see them anywhere in the main tank.
I have two Cleaner and 1 Coral Banded Shrimp. Could they be keeping the upper tank clean?
