Long story short after moving fish into new tank they developed ICH. The old tank is still set up and running, pulled all rock and inverts out but sand is still there. Can I run copper with sand in place? I know it will be trash after and I'm good with that. My fear is if I remove all sand I will stir up crap and then tank will crash or have to cycle again. I need to treat fish now not wait for a cycle.
