Hey everyone, just wondering what recommendations are for fallow periods. Had a complete wipeout about 6 weeks ago. Lost 2 tangs 2 clowns a 6 line and shrimp! Still unsure what caused it. I think it was velvet since it looked like the purple tang had sugar dusted on him. My LFS was convinced it was brooklynella. Either way it sucked. Any recommendations on my next steps. I want to avoid it as much as possible because honestly another wipeout might take me out the hobby completely. Running a skimmer, UV, carbon at the moment with weekly 20% water changes
