Well….lost all my livestock to velvet in a day(only three fish). Going to go fallow for 80 days to be extra safe. If you’ve ever gone through this, what have you done with your tank while it was empty? I’m thinking of upgrading lights, adding uv filtration and rearranging my rock scape. My biggest question is can I add coral (softies) while fallow or do I risk reintroducing parasites and having to restart the clock? 20gal aquatop aio cube
